Hello
Is there a way to stop the search process when a given number of hits is
reached?
I have a counter feature which displays how many docs match a query.
This counter is blocked; I mean that if there are more than 500 docs, it will
just display "more than 500".
I don't care about the exact amount of docs matched by the query, the order of
the hits or whatever...
What I want is to stop the search process when it reaches at least 500 hits in
order to improve performance...
(I want an average search time in about 50 - 100 ms)
I experimented with the following methods :
For the same query:
with search(Query query, Filter filter, Sort sort) hits=157691 docs in
searchingTime=2514 ms
with search(Query query, Filter filter, int n) (with n = 50) TopDocs totalHits
157691 in searchingTime= 2360 ms
For another query:
With search(Query query, Filter filter, Sort sort) hits=1208 docs in
searchingTime=750 ms
With search(Query query, Filter filter, int n) (with n = 50) TopDocs totalHits
1208 in searchingTime= 718 ms
For another query:
With search(Query query, Filter filter, Sort sort) hits=16174 cv(s)
searchingTime=1297 ms
With search(Query query, Filter filter, int n) (with n = 50) TopDocs totalHits
16174 in searchingTime= 1219 ms
According to this results, replacing the first method by the other has no
effect on either the search
time or total number of hits returned
Also the lucene version used now is 1.9.1 (but i work on the evolution to 2.3.2)
Thanks a lot
