Hey guys,
Sorry for such a simple question, but I am curious as to the differences in
caching between a
"combined" filter query, and many separate filter queries.
Here are 2 example queries, one with combined fq, one separate:
1) "/select?q=*:*&fq=type:bid&fq=user_id:3"
2) "/select?q=*:*&fq=(type:bid%20AND%20user_id:3)"
For query #1: am I correct that the first query will keep 2 independent entries
in the filterCache
for type:bid and user_id:3?\
Correct.
For query #2: is it correct that the 2nd query will keep 1 entry in the
filterCache that satisfies
all conditions?
Correct.
Lastly, is it a fair statement that under general query patterns, many separate
filter queries are
more-cacheable than 1 combined one? Eg, if I performed query #2 (in the
filterCache) and then
changed the user_id, nothing about my new query is cache able, correct (but if
I used 2 separate
filter queries than 1 of 2 is still cached)?
Yes, it is.
