Cfsearch error: status code -1706

Question

CF7.0.2 update level hf702-65114.jar (Standalone server on
Windows 2003)
Type: SearchEngine
Message: There was a problem executing the CFSearch tag with
the following collections.
Detail: Collection (status code): MyCollectionName (-1706)
Since re-creating a set of about 12 collections in a
different folder (same drive), I've been getting the above error
the first time CFSEARCH is invoked following an update of *any*
collection (not necessarily the one mentioned in the error.
Re-indexing or re-creating the named collection does *not* fix the
problem: CFSEARCH will continue to fail - so it's not corruption.
Re-starting the CF Search Service however does fix it... until the
next time one or more collections are updated.
I am now auto-restarting the CF Search Service using
cfexecute after each update but this is not ideal, and in fact just
now it seems to have had no effect: the tag has errored again
apparently in spite of the restart after the update.
I've searched for Verity status code 1706 but can find
nothing. Can anyone shed any light?

Answer 1

Sure:
1) Create a batch file (using Notepad but save file as
"restartCFsearch.bat") to restart the Windows service and make sure
the CF service account has execute permissions for it (if it's
running as local system then it will have)
NET STOP "ColdFusion MX 7 Search Server"
NET START "ColdFusion MX 7 Search Server"
2) Optionally create a function which executes the batch file
(or you could just put the cfexecute directly in the exception
handler, but creating a function will make it more re-usable):
<cffunction name="restartCFSearchService"
returntype="void" access="public" output="false">
<cfexecute name="[path to your batch file, eg:
D:\batch\restartCFsearch.bat]" timeout="30"></cfexecute>
</cffunction>
3) Wrap your cfsearch tag/function in a try/catch and test
for the error:
<cftry>
<cfsearch... >
<cfcatch type="SearchEngine">
<cfif findNoCase("There was a problem executing the
CFSearch tag",cfcatch.message)>
<cfset restartCFSearchService()>
<cfset sleep(3000)><!--- wait 3 seconds for the
service to come back up --->
<cfsearch...><!--- re-issue search --->
<cfelse>
<cfrethrow>
</cfif>
</cfcatch>
</cftry>
To pause before re-issuing the search I'm using

Hope that helps.
