Hi Hoss Erick,
Thx for your responses.
I found the bug in my code. It is not something todo with positions (As I

Hi,
Lucene doesn't find following value. Some issues with PhraseQuery.
indexed value: pink-I
Indexed tokens:1: [pink:0-5] 2: [pinki:0-5] 3: [i:5-6] (ex. explanation:
pink is a term 0-5 term-position)
And I have indexed in a field called fieldName.
My lucene search with the query [fieldName:pink
Strangely..
My lucene query: fieldName:pinki i finds document. (see i in pinki)

Hi ,
Of course this statement is very expensive.
--document.get(CAMPCATID)==null?:document.get(CAMPCATID);
Use StringIndex/FieldCache/something similar to implement category counting.

You can also think about clever indexing schemes with fields that
allow you to sort however you really need to, although I confess

You'll need to do it manually and not with Lucene.
Just grab all the results from Lucene and process them yourself.

I really lack this feature from lucene too.
Whatever the requirements from Mohammed, There surely I see some
improvements in search performance.
My argument here is, why not lucene provides a mechanism to be able to
provide custom document ids?

It seems anaylzers are never get called for UnTokenized fields(Seems no luck
either using PerFieldAnalyzer).
What should I do, If I would like to use analyzer for Untokenized fields.

But this BitSet strategy is more memory consuming mainly if you have
documents in million numbers and categories in thousands.

Hi,
You can use BooleanQuery.setMaxClauseCount() to set to your required
maximum clause count.
But ofcourse too big clause count is not advisable.
May be you need to find some strategy to reduce this range. Ex:Reduce date
ranges to 20060505 from including timestamp like 20060505120530 :)
