Hi all, I wrote my own custom query parser, and extended elasticsearch as a plugin, the code is in the following link.
query parser http://pastebin.mozilla.org/6172836 customized query http://pastebin.mozilla.org/6172837 plugin http://pastebin.mozilla.org/6172844 I used the default settings of Elasticsearch, and the document I PUT is { "test": "haha" } { "test": "ahah" } I used the query: { "query": { "backwards": { "test": "haha" } } And the error message I got is: [2014-08-27 13:26:41,678][DEBUG][action.search.type ] [Poison] [test][2], node[w4ORe_ERQBeOVpII3P9w1w], [P], s[STARTED]: Failed to execute [org.elasticsearch.action.search.SearchRequest@7e1416e] lastShard [true] org.elasticsearch.search.query.QueryPhaseExecutionException: [test][2]: query[filtered(BackwardsQuery: test:ahah)->cache(_type:test)],from[0],size[10]: Query Failed [Failed to execute main query] at org.elasticsearch.search.query.QueryPhase.execute(QueryPhase.java:162) at org.elasticsearch.search.SearchService.executeQueryPhase(SearchService.java:261) at org.elasticsearch.search.action.SearchServiceTransportAction$5.call(SearchServiceTransportAction.java:206) at org.elasticsearch.search.action.SearchServiceTransportAction$5.call(SearchServiceTransportAction.java:203) at org.elasticsearch.search.action.SearchServiceTransportAction$23.run(SearchServiceTransportAction.java:517) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:745) Caused by: java.lang.NullPointerException at org.elasticsearch.backwardstermquery.BackwardsTermQuery$BackwardsScorer.docID(BackwardsTermQuery.java:118) at org.elasticsearch.backwardstermquery.BackwardsTermQuery$BackwardsScorer.nextDoc(BackwardsTermQuery.java:133) at org.apache.lucene.search.Weight$DefaultBulkScorer.scoreAll(Weight.java:192) at org.apache.lucene.search.Weight$DefaultBulkScorer.score(Weight.java:163) at org.apache.lucene.search.BulkScorer.score(BulkScorer.java:35) at org.apache.lucene.search.IndexSearcher.search(IndexSearcher.java:621) at org.elasticsearch.search.internal.ContextIndexSearcher.search(ContextIndexSearcher.java:175) at org.apache.lucene.search.IndexSearcher.search(IndexSearcher.java:491) at org.apache.lucene.search.IndexSearcher.search(IndexSearcher.java:448) at org.apache.lucene.search.IndexSearcher.search(IndexSearcher.java:281) at org.apache.lucene.search.IndexSearcher.search(IndexSearcher.java:269) at org.elasticsearch.search.query.QueryPhase.execute(QueryPhase.java:156) ... 7 more I am very confused of it, could someone please point out what's wrong?
