Does SOLR support percolation
besides what BunkerMentality said, it is not hard to build your own percolator, what you need:
- Are the queries you want to run easy to model on Lucene only syntax? if so you are good, if not, you need to convert them to Lucene only. Built them, and keep them in memory as Lucene queries
- When a doc arrives:
- build a MemoryIndex containing only that single doc
- run all your queries on the index
I have done this for a system ingesting millions docs a day and it worked fine.
