I'm getting data with BDC in order to query it with Search Server. All is good, but I don't find how to compare two dates: my query looks like this:
ClaimDate =< 01/01/2011 AND [...]
Why aren't you using:
You query doesn't look like a fulltext query, but like a keyword query, it that correct? A reference can be found here to build the different queries: http://www.itidea.nl/index.php/example-of-using-the-spservices-search-web-service/
Probably the date format isn't correct either, I could be wrong, but I guess it has to be something like: 2011-04-08T13:45:47+02:00
If managed property in search service, try this
This should search for all files that have claim date between these two dates.
