Description Jim Melton 2005-09-25 19:09:22 UTC 
Consider the document

cat cat

and the query

("cat" && "cat") occurrences exactly 4

Currently, it returns true. Is this the desired semantics for FTTimes? If yes,
how do we explain it in the language document?

Significant progress was made on this issue at the face-to-face meeting of the
Full-Text Task Force in September, 2005.
Comment 1 Jochen Doerre 2005-11-07 15:59:40 UTC 
Decided in Sept05 F2F (Boeblingen) to restrict FTTimes to be applicable only to
words and phrases.

I made the following changes:

* Changed the schema of the FTTimes schema type to accept only FTWords as a
nested  selection.

* Changed the NL description of the function to match the arguments.

* Explicitly stated the requirement that the nested FTSelection is an FTWords.

* Added a check in the semantics if the AllMatches contains stringExclude; if
yes, XPST0003 is raised.


I don't think any other changes to the semantics are needed. I don't think it
can be further simplified, as the FTWords can be complex (e.g. all, any).
