added[5.0.0,Percolator queries modifications aren't visible immediately and a refresh is required]
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

percolator: Replace percolate api with the new percolator query Also replaced the PercolatorQueryRegistry with the new PercolatorQueryCache. The PercolatorFieldMapper stores the rewritten form of each percolator query's xcontext in a binary doc values field. This make sure that the query rewrite happens only during indexing (some queries for example fetch shapes, terms in remote indices) and the speed up the loading of the queries in the percolator query cache. Because the percolator now works inside the search infrastructure a number of features (sorting fields, pagination, fetch features) are available out of the box. The following feature requests are automatically implemented via this refactoring: Closes #10741 Closes #7297 Closes #13176 Closes #13978 Closes #11264 Closes #10741 Closes #4317

added[5.0.0,For indices created on or after version 5.0.0 the percolator automatically indexes the query terms with the percolator queries this allows the percolator to percolate documents quicker. It is advisable to reindex any pre 5.0.0 indices to take advantage of this new optimization]
