I know that fq's are used to improve performance by reducing the data set that you score.
I have read the documentation that says that non-cached fq's are created in parallel to your query, but would like to know more about how that is done. Does it do a match on all the FQ's, then AND the resulting doc sets and then once that is done score the query based on the resulting subset of documents? -- Andrew Lundgren lundg...@familysearch.org NOTICE: This email message is for the sole use of the intended recipient(s) and may contain confidential and privileged information.
