multifield queries dismax or...
Hi all,
I'm working to replace my old lucene java-based search functionalities with
Solr.
I implemented multi-field query search using the "dismax", but the query
seams to take to much time (if I compare with my old lucene queries).
There is another way to perform multi-field query in solr?
Following you can see the fragment og configuration of my solrconfig.xml and
a sample query I'm doing.
.......
<requestHandler name="partitioned" class="solr.SearchHandler" >
<lst name="defaults">
<str name="defType">dismax</str>
<str name="echoParams">explicit</str>
<str name="qf">text^0.5 features^1.0 name^1.2 sku^1.5 id^10.0</str>
<str name="mm">2<-1 5<-2 6<90%</str>
<!-- This is an example of using Date Math to specify a constantly
moving date range in a config...
-->
<str name="bq">incubationdate_dt:[* TO NOW/DAY-1MONTH]^2.2</str>
</lst>
.......
.......

Note that not only is pulling 10K documents out of the index (or even documentCache) slowing you down, but so is writing out and reading the response.

Hi Erik,
thank you for the fast answere!
I didn't take care abut the number of the output records.
I know 10000 recs are a lot, but i need these.
Actually if I reduce the number of the records the query is faster. so the
problem seams releted to loading the content from the index, at that poit I
have to change something in the logic of my process.
Thank you,
Regards
Alessandro

Returning 10000 rows/documents - maybe that is the speed issue you're
encountering?
Try adding &debugQuery=true to your request and look at the timings in
the response. What is the QueryComponent time? Try returning fewer
rows and see how the speed changes.
