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 [fieldN
Strangely..
My lucene query: fieldName:"pinki i" finds document. (see "i" in "pinki")

Hi Hoss & Erick,
Thx for your responses.
I found the bug in my code. It is not something todo with positions (As I
said in my first mail, I was using right position increments) and also
nothing to do with offsets. Offsets are just ignored, only useful for
Highlighter perhaps. Anyway I am not intere
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?

Hi Hoss,
Exactly in this scenario, I would love to use my custom generated document
id.
The array reference number is MyId & its value is some-interested-value
matched to MyID.
So,how can I generate custom document id.?

Yeap. I strongly support John.
I knew when I reopen indexes. Then what is the reason to wait for garbage
collector..
And that too, FieldCache uses WeakHashMap and that may lead some memory
leaks.

Actually I don't like well my proposed way of implementation.
I wanna play with score to implement the similar logic as I mentioned in my
solution.
But how?
Any suggestions, I would really appreciate. :)

But I also see importance of ignoring score calculation.
If you put it aside performance gain, is there any possibility to completely
ignore scoring calculation?

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 are right. There can be multiple indexreaders but only one indexwriter

You are opening IndexSearcher for each and every search request, which is
not adviasable.
Cache IndexSearcher or IndexReader.. This will surely improve your speed .

Hi,
PhraseQuery is not working as I wanted,when indexed with synonyms.
ex:
I have indexed name: "sony dsc-d cybershot" as following tokens provided
token positions.
1: [sony:0->4]
2: [dsc:5->10]
3: [dscd:5->10]
4: [d:5->10]
5: [cybershot:11->20]
So "dsc-d" is tokenized into 3 tokens "dsc

Hi,
Actually lucene does not provide you a straight forward Query to get UNIQUE
results.
But as far as I know, u can use HitsCollector & BitSet combination to
count/get unique results.

No.. I don't see your solution is performant..
If each lucene Document corresponds to a row in 'A join B' then Index
explodes..
Index size drastically increases.
Why not then creating two indexs A and B.
And search for A and then from obtained A documents information search in B.
It seems for me
Hi,
I would use index & search analyzers in this case..
"b-trunk" is analyzed & indexed as b,btrunk,trunk
Search term "b-trunk" is anlayzed using search analyzer as "btrunk" and
searched. U will find the result..
Similarly for 12412-235, 12412-121, 12412-etc , indexed as
12412,12412235,235 etc...

Hi,
I am getting OutOfMemoryError , while enumerating through TermEnum after

Just to provide you more information, I have almost 1 unique terms in

gettting OutOfMemoryError.
I set jvm max
OutOfMemoryError.
Any advise is relly welcome.

I am trying to implement category count almost similar to CNET approach.
At the initialization time , I am trying to create all these BitSets and
then trying to and them with user query(with a bitset obtained from
queryfilter containing user query)..
This way my application is performant..Don't u
query, using HitCollector docids, I will try to calculate
each category count.. I think it is self understandable..
What do u think??
Any advice is really welcome..
Note: Actually, I have around 2 unique cateogry ids..

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 :)
All t
But this BitSet strategy is more memory consuming mainly if you have
documents in million numbers and categories in thousands.
So I preferred in my project FieldCache strategy.

Hi,
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.
Lets say for Keyword or Unstored fields.
I basically would like to use lucene Sort functionality on UnTokenize

Hi,
You are wrong.
In ur case (If I ignore any updates to index) , One IndexSearcher object is
enough.
IndexSearcher is thread safe.
