Are there some specific solr-only bits of functionality that : would preclude vanilla-lucene code from accessing solr-created indexes? the notion that Solr "extends" Lucene is primarily in terms of the HTTP API it provides, but there is lots of code in the Solr code base that extends the fuctionality of Lucene in various ways ... FunctionQueries for example, and support for them in the SolrQueryParser (which is a subclass of the Lucene QueryParser). If your primary concern is that you want to allow people writting apps using the raw Lucene APIs want to be able to access your index, your only real concern is in how you design your schema ... whatever analyzers you use on text fields will need to be available to the other clients, if you use the any of the complex field types, (sortable ints, dates, etc) then those other apps will need to know how to convert values before querying those fields. in addition to the solr.war, the solr distributions include a jar containing all of the stock code that ships with Slr -- primarily for compiling against when building plugins, but that same code JAR could be used by standalone Lucene apps to access the various TokenFilters and FieldTypes that Solr provides if you use them in your schema. -Hoss

possible FAQ - lucene interop
Hello all: We've got one java-based project at work using lucene. I'm looking to use solr as a search system for some other projects at work. Once data is indexed in solr, can we get at it using standard lucene libraries? I know how I want to use solr, but if the java devs need to get at the data as well, I'd rather that 1) they be able to use their existing tech and skills and 2) I not have to reindex everything in lucene-only indexes. I've read the FAQs and some of the mailing list and couldn't find this question addressed. Thanks. -- Michael Kimsal http://webdevradio.com
