How to build a search engine in the database?
Hi there,
say I have 3 tables:
1. Table_empl: idEmpl, fname, lname, dob...
2. table_department: idDpartment, idEmpl, departmentName, section...
3. table_fligths: idFlight, idEmapl, departure date, destination, carrier...I would like to provide the end-user a text box (in my GUI) where he can write whatever he would like to get info about. If, for example, he'll write: british-airways, I expect the system to search everything in the db that matches this input.
Question: How can I design such a search engine that retrieve information from every possible table in the db with reference to every column.
thanks for any pointers
thanks darted for your reply. so what do you recommend? should i give the end user all names of tables and columns and ask him to choose from the list and than build a query based on that?
this is optional but i'd rather have one exec button and to return all possible results from the db. if (in the example i provided) it found 'british airways' in the carrier - than that a result. if it founds 'british' in the lname of table_emple - that's another result. so the output should be something like:
found 2 matches:
1. british airways, 10/10/2006, LHR
2. British, John, 12/01/63,
any idea how to build that?

How do you add search engines to the Smart Search bar?
The whole point of an omnibar is so you can easily search a variety of search providers without having to go to their website first. For instance, in every other web browser I can type "i Oranges" and get pictures of oranges from Google Images. Or I can type "a Cookbooks" and instantly search Amazon for cookbooks. In every other web browser, in fact, I've been able to do this since at least 2010. What's the problem Apple? Can you seriously not figure out how to implement this? "Smart Search" isn't smart at all if I'm going to be stuck with the default 3 search engines.
I really hate when Apple pulls crap like this and I will be switching back to PC next time I upgrade. "It just works" has become a thing of the past and OSX seems to work against me more than it works for me. I shouldn't have to fight my OS to make it do what I want. Ridiculous.Whomever told you to hide text is leading you down the wrong path. Doing dirty tricks like that may help you in the extremely short term but the bigger search engines are smart enough to figure out what you're doing. Dirty tricks are a great way to get your site banned from the search engines.
The best way to get good results is to make sure all important text is actually text on the page (not images), have fresh content (blogs are great examples of this, they tend to do well on search engines), and find good ways to get other sites to link back to your site (link farms are not what I'm talking about but think along the lines of reviews, interviews, forum signature posts, etc.).
Be very wary of people telling you they can guarantee you first page results in search engines. They may do that for a short while but search engines are constantly evolving and can drop you as quickly—if not quicker—than pick you up.
It takes time to get a site in the top rankings but there are other methods out there that are better in the long run. -
When Firefox 8.0 installed it has automatically changed my address bar default search engine to Yahoo7 which is crap. I can not change this back. So when I start FF it opens to my google home page, when I type a subject and search the results are displayed in a Yahoo 7 results page, not google. I am not talking about my default home page or the search bar to the top right. This is still google.
The settings in about:config do nothing.
This was fine until FF 8.0.Thanks dmcritchie,
Nice effort but that answers a different question about fixing the add-on Yahoo toolbar.
Pernich and I want to know; If you type search criteria directly into the address bar and hit enter, how to change that search engine from Yahoo to Google.
Otherwise I too will go back to using Google Chrome, even though I really like FF8.0
please help -

How do I get rid of ZoneAlarm search engine in the address bar and middle-of-page search box?
I downloaded ZoneAlarm firewall. It has you install Chrome and choose its search engine when you download. I'd heard these were easily removed afterward. I reset Google in the upper right search bar.
Now Firefox starts OK, but each time I use a tab to open another window the ZoneAlarm search is in the address bar and the center search box, and Google search is in the upper right search bar. How can I get rid of all ZoneAlarm search everywhere?
I have the latest version of Firefox and Windows 8.1.You can check if you have the ZoneAlarm search engine file in the browser\searchplugins folder in the Firefox program or in the searchplugins folder in the Firefox profile folder.
You can use this button to go to the currently used Firefox profile folder:
*Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)
You can delete the search.json file and possible search-metadata.json and search.sqlite files in the Firefox profile folder to reset the search engines to the default.

Firefox will rebuild the search.json file from the default search engines in the "browser\searchplugins" folder in the Firefox program and the searchplugins folder in the Firefox profile folder. -

I want google as my search engine, not Bing. But no matter what I do in "Manage Search Engines," Firefox seems to reset to "Search the Web," which uses Bing.
How do I make Google the default search engine in the "Search the Web" feature of the search bar; or, how do I remove the "Search the Web" feature of the search bar so that "Google" can be default? When I move "Search the Web" down and "Google" up, the search bar resets every time Firefox reloads.Sometime Bing is not located in the Add/Remove programs section of the control panel.
6 Easy Steps to Remove Bing from Mozilla Firefox:
1. Click on the "inverted triangle" located to the right of the orange Bing icon.
2. Select the option "Manage Search Engines...". (A pop-up window will appear titled "Manage Search Engine List.)
3. Select "Bing".
4. Click the "Remove" button.
5. Select the desired search engine from the list.
6. Click "OK"
All Done.... :-)
Happy Searching...

How do I add a search engine to the search bar from a hard disk file?
I want to add a search engine to the search bar from an XML file on my hard disk. "Manage Search Engines" from the search bar drop down list only appears to allow adding search engines from web sites.
Thanks.Hmmm. This didn't work. I even re-booted, and Firefox still doesn't show the search engine.
It was actually an update to an earlier engine, and I foolishly removed the old version rather than just updating it.
Is there anything elsewhere (eg. the registry) that might be preventing this? -
seems self explanatory to me. I don't know what else to say.
You can check if you have the ZoneAlarm search engine file in the browser\searchplugins folder in the Firefox program or in the searchplugins folder in the Firefox profile folder.

How do I change the default search engine in the address bar?
I am trying to change the default search engine in the address bar to Scroogle SSL, I have tried editing about.config but it either goes to Google or on rare occasions it has opened to Scroogle SSL and the address bar shows https://ssl.scroogle.org/(+whatever was entered), while the main window shows a proxy error .
I have an idea that something needs to be added at the end of the URL in about.config to actually make it search.
Can anybody tell me what the specific settings would be to get this working?
I have Scroogle SSL in the search engine list but I want to remove the search box to save space.
Also I cannot get the search to open in a new tab even though browser.search.openintab is set to True.
Thanks in advance.
== Operating system ==
XP-SP3Hi, having tried both ways myself what you say is true but that is not the source of my confusion.
(In fact I discovered that when I set the same thing up in Opera10.53 everything up to the ? appears on one line in the setup and the Gw=%s on another.)
What I cannot understand is why, if I am using Scroogle SSl search it is opening the OpenDNS guide.
If I use my Scroogle SSL home page it opens a minimal Google search page, the same thing happens if I use the search box. I expected this would be the same as well or am I missing something?
OpenDNS is preferable to Google but not what I was looking for.
Since I started writing this I have just discovered that changing the keyword.URL does not affect this.
Earlier I recovered my system from an image which undid the changes that I had made to about.config, I have run searches both before and after I edited it again. Both times I finished up on OpenDNS? -
How do I set Google as the default search engine in the URL search field (now have Yahoo)?
I'd like Firefox to use Google as the default search engine for the URL search field, instead of Yahoo as I currently have. I've tried to find a place to reset this in Preferences but can't find a solution. Would be very grateful for any advice. Imagine it's simple.
NB: I'm talking of the left search field, not the right search engine one where it's easy enough to define.You can reset the prefs general.useragent.override and keyword.URL on the about:config page.<br />

When I initialize Firefox Bing comes up as the Search Engine in the Search box. I know I can pull down to get others. Is there someway for me to specify Google as the one displayed when Firefox initializes? Thank you.

How to build custom search using API - 10.1.2
Hi,
I have been looking through some documentation and i can't seem to find how to use the API in portal 10.1.2 to create a custom search. Any help or samples would be appreicated.
ThanksThe Search API is a new feature in 10.1.4. In older version a custom search portlet was provided, no API.
<br><br>
You can build a search engine yourself in Portal 10.1.2 by using the Oracle Text API. The search engine should implement security however which can be quit difficult to accomplish. It is not impossible however.
<br><br>
In most cases it is has less impact to upgrade to release 10.1.4 then to build a search engine yourself. My advice would be to install 10.1.4 on a test system and play around with the new search API. You can then decide whether it is worthwhile to upgrade to 10.1.4 where you profit from several nice new features. -
How to set another search engine in safari?
hi all
can anybody tell how to set another search engine than google/yahoo in safari (e.g. Bing)?
thank youAt this stage, I don't know of any workarounds (or available plugins) for Safari for Windows 4.0.4 that allow you to put a different search engine option in the search field.
The workaround I've been using is to pin a Bing window into my Top Sites.
You can send an enhancement request to Apple about it. Although it doesn't look to be set up for it, if you bring up your Menu Bar and go "Help > Report bugs to Apple", you can use that bug report form to ask for enhancements. I was skeptical about that to begin with, but apparently they check that for feature enhancement requests, according to the following document. (It's mentioned right down the very bottom.)
