Lucene Twitter Demo
-------------------

To run demo, clone repository, build the two source files (TweetIndexer and TweetSearcher). 

Note: You will need to add the Lucene library to your classpath before compiling. See the "Setting your CLASSPATH" section of this page: http://lucene.apache.org/core/3_5_0/demo.html 

Run indexer first:

java TweetIndexer <index directory> <csv data file>

Once indexing is completed, run the search demos:

java TweetSearcher <index directory> <expected number of hits>
