Thread:Extension talk:CirrusSearch/Problem with MW 1.24

I've upgraded my site to use MW 1.24.0 with ElasticSearch 1.1.2, CirrusSearch 0.2 and Elastica 1.3.0.0. I was previously using CirrusSearch on 1.23 without any problems. Since the upgrade searches are now failing. Looking at the debug log I'm getting:

Search backend error during full_text search for 'test' after 6. SearchPhaseExecutionException[Failed to execute phase [dfs], all shards failed; shardFailures {[WE7or35fTI2Z2PhOexLS8A][wikidb_content_first][3]: SearchParseException[[wikidb_content_first][3]: query[filtered(((all.plain:test | all:test^0.5) all_near_match:test)~1)->cache(namespace: �

Any thoughts as to what has gone wrong here and how I can fix it?
