Hello
Query I
Does the order of query play role in searching
example:doc has fields
rollno(pk), name, marks
Query : marks=90&rollno=2&name=abc
Query :rollno=2&name=abc&marks=90
which query processing will be more efficient.
is it work like search doc field by field , it will look for doc havi
Query I
its written "to do a "search within search", so that the second search is
constrained by the results of the first query"
we can use boolean query.
So doesn't it mean the order of query ll be preserved

Hello Erick,
I was trying to optimise the searching.
Basically my data is like field1 has less no of docs matching compared to
field2, which has larget sets.
So if search goes by order to order, then i can make field1 to be search
first, (by making order of boolean query such )and from thr the
Hello Joseph,
Yes this would work .Range queries could be used for range searches.
But this is very expensive in terms of performance.

Hello ,
Can we use subset of documents , for searching .
Lets say I
have hash map of
P1 -1,2,3,4
P2 - 3,4,5
P3-7,5,3
Now I have an
documents in lucene index stored as
1-P1
2-P1
3-P1,P2,P3
4-P1,P2
5-P2,P3
7-P3
..
..
when i search docs with P2 I get 3,4,5
Now I
want
Hi ,
I have 4 query search fields.
case 1 : if i use one search
field to make a query filter and then use the query filter to search on
other 3 fields so as to reduce the searching docs subset.
case 2: i use
all query parameters using boolean query , whole of index will be searched.
Which
hi ,
1. whether any search query, will scan for all documents in the
lucene indexes
2.
I want to search query faster.So I thought of if I
could reduce the number of docs , lucene needs to search for , when given
some search parameters. It would act lil faster.
Can we make subset

you can use query filter for that purpose .

I am also having a similar requirement .But its other way round.
Basically ,I have indexes in FSDirectory and which is transferred to
another machine on regular basis. But now for the reason of faster
searches, it would be better to copy the indexes onto RAM. (RAMDirectory).
Not sure of how it c
Hello,
I am little confused on the stored and index part of lucene
How it actually stores the indexed field and stored field
Is it that for every field indexed , all the store fields added .I mean do
we create diff indexes for every indexed field ,replicating the stored field
in each of th
some of the stored
fields use a FieldSelector.
http://wiki.apache.org/lucene-java/ImproveSearchingSpeed has good info
on making searching fast.

Hi,
I am facing the problem
The line in the loop is going very slow giving me a performance hit
for (int i = 0; i < hits.length; ++i) {
int docId = hits[i].doc;
Document d = searcher.doc(docId); //problem
}
How can I improve
dCache it'd be a nice thing to do.
Hope that helps.

Hi ,
I am using lucene 3.0.3.
It seems like either the lucene indexes are not getting optimized properly
as the files created in lucene index dir is growing with every doc added
Please let me know the way to restrict the files and segments created .
merge factor is10
max merge docs is21
ng
around with RAMDirectory?
Anyway, you appear to just add docs to the file based index, so surely
it will keep growing? You could try optimizing the file based index
but that is unlikely to gain you a huge amount unless it holds deleted
docs.
