Hello, I have some failed attempts in getting it all up and running. I have tried the following: 1. Using the couchdb-lucene-0.4-jar-with-dependencies.jar.gz file Getting it running didn't do the job, the readme's on github mention a bin/run which i don't seem to find, the same goes for the external python program. Nevertheless, i did get it running by using the following CouchDB configuration: [external] fti=/usr/bin/java -Dcouchdb.lucene.dir=/var/lib/couchdb-lucene -jar /usr/local/lib/couchdb/lucene/couchdb-lucene-0.4-jar-with-dependencies.jar -search [update_notification] indexer=/usr/bin/java -Dcouchdb.lucene.dir=/var/lib/couchdb-lucene -jar /usr/local/lib/couchdb/lucene/couchdb-lucene-0.4-jar-with-dependencies.jar -index [httpd_db_handlers] _fti = {couch_httpd_external, handle_external_req, <<"fti">>} Of course the data directory was writable. It did, however, fail in the end but Java was taking CPU time for sure but it never wrote a single byte anywhere. Issuing a query returned a CoucDB-Lucene not available error, which comes from http://github.com/rnewson/couchdb-lucene/blob/b258c33c956126a130d2b90effc106668f54879e/src/main/java/com/github/rnewson/couchdb/lucene/Search.java The second attempt was with Maven following the readme on the github (after i cleaned the previous mess), but different approaches and sources (either cloning with git or the 0.4 tgz) failed as well with Maven spitting out the following messages: [INFO] [compiler:compile {execution: default-compile}] [INFO] Compiling 17 source files to /usr/local/lib/couchdb-lucene/rnewson-couchdb-lucene-e0d8130/target/classes [INFO] [resources:testResources {execution: default-testResources}] [WARNING] Using platform encoding (UTF-8 actually) to copy filtered resources, i.e. build is platform dependent!

The classes and test-classes directories, however, where present. This machine is running the latest Ubuntu and already has working CouchDB and Solr instances happily running. I therefore assumed installing Maven2 using apt-get install maven2 would do the job on a fresh cloned checkout: 1. Install Maven 2. 2. checkout repository 3. type 'mvn' 4. configure couchdb (see below) Can someone please shed some light on this mystery so i and anyone else stumbling on this thread will know how to continue the installation?
