Subject Faceted Search Slows Down as index gets larger
Date Fri, 04 Jun 2010 14:31:18 GMT
Hello,

I have been dealing with real-time data.

As the number of total indexed documents gets larger (now 5 M)

a faceted search on a text field limited by the creation time, which we use
to find the most used word in all these text fields, gets slow down.


query string: created_time:[NOW-1HOUR TO NOW] facet.field=text
facet.mincount=1

the document count matching the query is around 9000.


It takes around 80 seconds in a decent computer with 4GB ram, quad core cpu

I do not know the internal details of term indexing and their counts for
faceting.

Any suggestion for speeding up this query is appreciated.

Thanks in advance.
