A problem of searching word "3D" with Lucene.net

Hi All,

I have created an index file with CLucene. I'm now using Luenen.net 2.3.2
to query the index. While searching key word "3D", it returns 0 results.
But my target file do have includes words like "3D model".
If I search a pure numeric, it do return correct results.

Anyone knows how to search "3D"?

Thanks a lot!
Qizhen

Have you tried querying the index using Luke? Check which analyzer you used....

What Analyzer did you use to create the index?
Some Analyzers remove digits when creating the indexed tokens.

I used the standard analyzer for both indexing and searching.

I didn't try Luke. But I tried CLucene for searching. CLucene can return
results for 3D. So, this could be Lucene.net problem only.

If you index the string "3d model" using CLucene and use Luke, you will see
that there are 3 terms in the index "3" , "d" and "model"
(it has to be "3d" and "model").
So, the problem is due to the incompatible StandardAnalyzer of CLucene.

I see.

Whose behavior is correct? Lucene.net, CLucene is correct, or there is not a
standard at all.

Thanks,

Lucene.Net works just as Lucene Java. Problem is with CLucene.
