How to search for exact string?
Is there any way to search for the text string exactly as I enter it? Like 'exact search' in the OSS notes?
For example, I'm trying to find the forum posts regarding the Excel 2007 file format XLSX. By XLSX the search finds hundreds of entries, but most of them are not even close. For example, this was one of the top results: /thread/1078918 [original link is broken]
Why is it getting picked up when 'xlsx' doesn't even appear there? We are frequently complaining about the users who don't use search before posting, but, frankly, if it works like this, I can't blame them...

"Why is it getting picked up"
I regularly use this to (re)find threads where I remembered a specific comment or even spelling mistake.
Perhaps a better option in your case would be to use an AND between individual terms.
I generally tend to edit the search string parameters directly, as it seems to cache previous results and do a search within a search. That might be an option for you as well though.

Julius

How to search for particular string in array?
I am struggling to figure out how to search array contents for a string and then delete the entry from the array if it is found.
The code for a program that allows the user to enter up to 20 inventory items (tools) is posted below; I apologize in advance for it as I am also not having much success grasping the concept of OOP and I am certain it is does not conform although it all compiles.
Anyway, if you can provide some assistance as to how to go about searching the array I would be most grateful. Many thanks in advance..

Is that right?
Can you use an ArrayList<String> instead of a String[ ]?
To find it, you would just do:
for (String item : myArray){
if (item.equals(searchString){
// remove the element. Not trivial for arrays, very easy for ArrayList
}Heck, with an arraylist you might be able to do the following:
arrayList.remove(arrayList.indexOf(searchString));[edit]
the above assumes you are using 1.5
uses generics and for each loop
[edit2]
and kinda won't work it you have to use an array since you will need the array index to be able to remove it. See the previous post for that, then set the value in that array index to null.

How to: Search for a string in entire movie project?
I used a copyrighted name a few different places as I was creating a very long and complex game. I have since removed it from the game where it was previously showing up but when I search the exe, it's still there in a few places. Is there a way to search the entire movie project and all content, all scripts for a particular string? For instance "Microsoft".
If so, I cannot find a way and could use some direction, even if it's an xtra I need to install that adds this capability.
Thanks!!!!!Scripts are easy. You open any script window and hit Ctrl + F and enter your search term in the Find box, ensuring the "All Casts" radio button is checked.
For text and field members you'll need to write a script that does the search for you. If you were clearer about what you want to happen when you find your search term in a text member then someon could help you with how to perform this. I know there is already code posted to the forum somewhere about how to examine every member of every castLib checking the member type - which would be a very good place to start. -
FQL query text to search for exact string
Hi
we are using SharePoint 2010 with FAST search...
I'd like to be able to search for this exact string that contains parentheses... "(ABC)"
I thought it would be:
ManagedProperyName:"(ABC)"
this returns results with just ABC ... it ignores the parentheses... i need to only show documents with "(ABC)"For exact query you can use equals. For example MPName:equals("<term or phrase>")
However, in your case the parenthesis is considered a special characters which are stripped off during document processing and at query time. -
How to search for a string in a DefaultListModel
I have a list of names stored in a DefaultListModel and would like to know how i can search for a particular name
i assume i would have to use the method below but not sure of how to implement it
so basically i would have a texfield where a user can type in a name to find in the list
public int indexOf(Object elem)
Searches for the first occurence of the given argument.
Parameters:
elem - an object.
or i might be wrong
Any ideas of how to write this mechanism
Can anyone please help on thisThe DefaultListModel uses a Collection of some sort (Vector at present) to store data. You can get this data in two ways:
DefaultListModel model = (DefaultListModel)list.getModel();
Enumeration e = model.elements();
while(e.hasMoreElements()) {
if (e.nextElement().equals(elem)) return;
}or
Object[] array = model.toArray();
for (int i = 0; i < array.length; i++) {

Hi All,
My requirement is to search string Like "List Price",if the input field is having this string at any place i need to transfer input value to target.
Could any one help me on this writing a UDF for this.
Input : Final List Price Vendor
check for :List Price
then pass the other values to Target.
Thanks,
MadhuHi,
Check with this UDF
public String Search(String a,String b,Container container)
String c;
int i;
i = a.indexOf(b);
if(i == -1)
c = " ";
else
c = a;
return c;
Here a is the input and b is the search string.
0r
if the value of search string doesnt change dynamically then the UDF can be like this
public String Search(String a,Container container)
String c;
String b;
b = "List price"
int i;
i = a.indexOf(b);
if(i == -1)
c = " ";
else
c = a;
return c;

How do i search for a string in a txt file using java??
How do i search for a string in a txt file using java??
could you please help thanks
JRegular expressinos work just fine, especially when
searching for patterns. But they seem to be impying
it's a specific group of characters they're looking
for, and indexOf() is much faster than a regex.If he's reading from a file, the I/O time will likely swamp any performance hit that regex introduces. I think contains() (or indexOf() if he's not on 5.0 yet) is preferable to regex just because it's simpler. (And in the case of contains(), the name makes for a very clear, direct mapping between your intent and the code that realizes it.) -

How to search for upper/lower case using string using JAVA!!!?
-I am trying to write a program that will examine each letter in the string and count how many time the upper-case letter 'E' appears, and how many times the lower-case letter 'e' appears.

what i have so far:
[code]
public class Project0 {
public static void main(String[] args) {
String[] uppercase = {'E'};
String[] lowercase = {'e'};

System.exit(0);
// if the inputWord is contained within uppercase or
// lowercase return true
if (wordIsThere(inputWord, lowercase))
isOrIsNot = "Number of lower case e's: ";
if (wordIsThere(inputword, uppercase))

How can I search for a string like a partial IP address in the global search
When searching for a string like "10.255." the global search finds messages containing "255" or "10" and both.
This happens no matter whether quotation is used or not.
When quotation is used it probably will match on the given order as well, but beeing in the timezone '+0100' the string "10" is always found first (in the email headers...).
Is there a way to tell the global search not to use '.' or any other character as whitespace?When searching for a string like "10.255." the global search finds messages containing "255" or "10" and both.

The top portion can search for the location of a string, while the bottom portion is to locate the position of a character. Both can search for a character.
The position of the character within the file is displayed in the indicator(s).

How to search for a variety of characters
I am working on a document wherein a script I ran has applied differential results to page indicators. I am trying to ensure that I have easy accessibility to indexing in an e-book format, and so I am doing the following:
1.) Inserting notes at physical page breaks in the print layout in InDesign
2.) making those notes visible
3.) applying the "page" style to them, which I have set to display hidden in my CSS but will allow me to insert anchor points for a hyperlink index
The problem is the note shows up differentially. Some say:
{~?~PG: @##@} while others show {~?~PG: %##%} where ## represents some page number. The @##@ received the page style properly, but not the %#%. What would be the GREP approach to searching for every instance of {~?~PG: %##%} and applying the page style to it?
I know how to make sure that the page style is applied. I know that I'd use (\d+) for the numbers. I don't know hwo to represent the brackets, tildes, question marks, or other characters. Is there a good reference for this somewhere or perhaps a tutorial? I hate to bug the forum community with it. I just don't know where to go to get the info I need.
Edit: To be clear, I'm trying to search for the string
{~?~PG: %##%}
All of the characters in the string are the same each time, but the numbers are sequentially higher and higher. There are hundreds of these in my document, so replacing each manually is taking a long time. Thanks for any feedback.
Edit #2: After a lot of trial and error, I nailed it. This worked for me:
\{(.+)\%(\d+)\%.
I left the "change to" blank and in the big Change Format window, I added character style "page", though of course this is going to be different for you depending on how you have the name of that style set up in your CSS file if you're making an e-book too. : )
Message was edited by: 1John5vs7You should definitely look into full-text search. The idea that Kalman floated is doable, but it require a lot more work on your part. Full-text does a lot work for you, for instance handling inflections, so that a search on "goose" will get a
hit on "geese".
If you have never worked with full-text search before, I recommend to get your hands on this book:
http://www.sqlservermvpdeepdives.com/
http://www.amazon.com/SQL-Server-MVP-Deep-Dives/dp/1935182048/ref=sr_1_1?ie=UTF8&qid=1400851023&sr=8-1&keywords=sql+server+mvp+deep+dives
This book is a collection of chapters written by a number of SQL Server MVPs, and all our royalties goes to War Child International, so you are supporting a good aim if you buy this book.
Chapter 13 by Robert Cain is an excellent introduction to full-text search, although it does not handle Semantic Search added in SQL 2012.
As it happens, my chapter, describes a solution of what Kalman had in mind, although it aimed for the case where you want to permit users to search arbitrary character sequence, and that is not want you want.
