Subject [jira] [Commented] (LUCENE-4317) does not reuse its inlined Keyword-TokenStream
Date Tue, 21 Aug 2012 11:47:38 GMT


Robert Muir commented on LUCENE-4317:

In addition, the "Robert solution" still does not solve the numeric problem of recreating
NumericTokenStreams over an over.

It could: the problem here is the same, that it uses a special tokenstream instead of being
a normal one integrated into the Analyzer.
if it was fixed in the same way, it could have better QP support etc out of box as well (e.g.
numeric queries work by default or whatever).

> contains a inlined Keyword-TokenStream. Unfortunately this one is recreated
all the time, although one reuses the same Field instance. For NumericTokenStream
reuses it, but the Keyword one not.
> We should apply the same logic and lazy init the TokenStream with a setter for the String
value and reset(). This would be looking identical to SetNumeric(xx).
