It looks like you are seeing some peculiar behavior so you should probably open a ticket with Customer Support. The FTIndexer log entry you included is showing a join or vendor form scan operation that did not find any changed records, but that's not particularly unusual.  What confuses me is your scan interval seems to be off because the log entry timestamp matches the "updated since" time.  There should be a gap there of at least a minute or two where the server is looking for changes that occurred some time earlier.  You should probably check the scan interval on schema 461 to determine what it is set at.  Noiw, for the FTS setting you added on a field, was that on a join or vendor form?  If it was on a regular form, you should have traceability in the FTIndexer log file.  Did you see any entries in the FTIndexer log file at the time you saved the change in Developer Studio?  You can also utilize the FTS Plug-in log to determine if there are any downstream problems that are affecting the server's ability to complete the operation.  If you provide Customer Support a SQL, FTIndexer, and FT Plug-in log from the time of your operation, they should be able to analyze what happened.  Or, you can post those log files here.  Hope you get it solved . . .

Are you in a server group environment?

If it is the plugin from 7.6.04 (no sp), you should use (at least) the one from 7.6.04sp2 which is more stable.

("\ARSystem\pluginsvr\fts\ftsplugin7604_build002.jar").

In the "ranking" form is FTS indexing pointing on the server which handles the "administration" operations? Well as you have one running, all operations should be set to this one.

On 7.6.04 we had an issue with FTS indexing not working if the indexing wasn't "following" the "administration" (basically those two tasks on the same server).

Did you try to create a simple regular form, with a character field, setting it to "MFS+FTS" and then create a couple of entries for it?

Then search this form using this character field logging SQL, it'll seach using FTS index and it should be mentionned in the SQL logs.

I see, did you check ranking and did the little test?

Weird...

Weird...

Can you activate debug level for FTS?

/arsystem/arserver/pluginsvr/fts§log4j_pluginsvr.xml

Change all level to all or debug.

<level value="warn">

to

<level value="all">

for example.

Same thing for "plugin" log entry in the same xml file:

<priority value ="error" />

to

<priority value ="all" />

You'll need to stop / start arserver I guess and then activate "fts" logs  .

Some questions:

Do you have anything pending in form "application pending" or in "CAI" forms?

How many threads did you allocate to escalations?

Nope no idea
