[jira] [Commented] (SOLR-6502) Custom search component to reduce
recall of 'edismax' query.
[ https://issues.apache.org/jira/browse/SOLR-6502?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14128848#comment-14128848 ]
Walter Underwood commented on SOLR-6502:
----------------------------------------
I always thought of this as variable precision rather than variable recall.
I've thought about calling it "adaptive precision", but that is probably too big a claim. It might apply if there were multiple steps for mm, like 100%, 50%, and 1.

> Custom search component to improve query performance by reducing the normal recall of the 'edismax' query. This component will set the 'mm' (minimum match) parameter to 100%, requiring all keywords to match. If there are no matches, 'mm' is set to 1 and the query is retried. This component is registered in solrconfig.xml as '/LowRecallsearch'.
