percolator: renamed `percolator` query to `percolate` query
2016-04-19 09:59:09 -04:00
deprecated[5.0.0,Percolate and multi percolate APIs are deprecated and have been replaced by the new <<query-dsl-percolate-query,`percolate` query>>]
Percolator refactoring: * Added percolator field mapper that extracts the query terms and indexes these terms with the percolator query. * At percolate time these extracted terms are used to query percolator queries that are like to be evaluated. This can significantly cut down the time it takes to percolate. Whereas before all percolator queries were evaluated if they matches with the document being percolated. * Changes made to percolator queries are no longer immediately visible, a refresh needs to happen before the changes are visible. * By default the percolate api only returns upto 10 matches instead of returning all matching percolator queries. * Made percolate more modular, so that it is easier to add unit tests. * Added unit tests for the percolator. Closes #12664 Closes #13646

For indices created on or after version 5.0.0-alpha1 the percolator automatically indexes the query terms with the percolator queries. This allows the percolator to percolate documents more quickly. It is advisable to reindex any pre 5.0.0 indices to take advantage of this new optimization.
