Thanks, everyone who replied -- you all have been helpful. I'll try tweaking the memory size first before trying new search engines.

You may want to check how much memory is allocated to the JVM that is running the search service. You can increase the memory allocated in the config file (the maxheap size), which will alleviate some of the symptoms of the problem.

    At a previous job, we moved from Lucerne to elasticsearch, which
    really well.  It did index the contents of PDFs and other files
    also.  Hope this helps

        Indexing is no problem, but searches sometimes are a problem.
        A search would come back quickly, and the other times, it
        doesn't. According to the logs, threads would get stuck in a
        waiting state after executing the cfsearch statement. I think
        this happens if there are several people trying to run
        searches at the same time.

        Hi Angeli,

        Solr may just need a little tweaking.  Do you know why it's
        hanging, or when?  Is it during queries or indexing? 
        Anything interesting in the logs?  It may need more memory,
        or there could be an issue reading some files that you're
        indexing.  I'd check into the logs to see why Solr is
        struggling before undertaking a retrofit of the search
        engine, it might save you a lot of time and resources, and
        Solr is already one of the most popular enterprise search
        engines.

        If you're certain you want to change search engines, you
        could (relatively) easily use any one with a java client
        library or web services/REST-based API.  Elasticsearch is
        popular.  It's based on Lucene just like Solr is though. :)

        Hope this helps.

        Take Care,

        Seth

            Good afternoon, folks.

            I'm wondering if anyone have has problems with searching
            via <cfsearch>
            and Soir on ColdFusion 11? One client I work for has
            about 1,000 PDF
            files (some dozens pf pages long) indexed nightly. Daily,
            an average of
            about 1,000 searches would be run through the collection,
            some just
            single words, and some phrases, some using "or". 
            Sometimes, the Soir
            search engine would slow down and get hung up, and
            occasionally we have
            to bounce Coldfusion's Add-On service. We didn't have
            this kind of
            problem when we were using Verity on an older version of
            ColdFusion. Is
            Soir normally this flakey?

            Also, are there any alternatives to Soir? What about
            Lucene... can it
            index PDF files?

            Thanks,
            Angeli Wahlstedt
