hi..

old query:

select?q=testing&fq=user:1

how do I convert into new query.

I want to search the term testing.

if I change the query like below I believe it wont search the word testing..

select?q=1&qf=user

any way to do it..

thanks.

Marc, I would first filter by age since you know that is going to result in fewer rows to search than a binary, m/f search. Once you’ve narrowed the fields down as much as you can then apply the filters.

select?q=40&qf=age&fq=gender:male

SOLR 1.4 actually comes with a bunch of new filtering improvements where they apply filters during the query process. In this simple case it might do it for you in the background but I can’t be positive. Benchmark it both ways and see what happens.

Interesting read.
How would you create a query with more than one element in this fashion?
e.g. you want to find every male person with the age 40

with the old query:
select?q=+&fq=gender:male AND age:40

with the new query:
???

Thanks,
Marc

Jim,

I have benchmarked the performance differences between the old and new queries as well as their use of the fieldCache as well as the differences between single indexes and multi-core indexes.

Does your new query style take advantage of the filterCache as well a the old one did? I guess if overall perf is 100x better who cares.

Nice, We do similar things with our queries. I’ll see if this applies in our case. +1 to understanding whats going on before optimizing!
