To run unit test suite

lucene_tester is built using the Google Testing Framework. you can run the test suite on unix with the following command run from the repository root::

    $ build/src/test/lucene++-tester

the test suite can also be run from the repository root on NT systems, but the required DLL files must manually be copied into the test binary path before executing, otherwise you will recieve errors telling you that required libraries cannot be found.

    $ build/src/test/lucene++-tester

To run the demos

Start by indexing a directory of files - open a command prompt and run

Once the indexer has finished, you can query the index using searchfiles
    ./searchfiles -index 
This uses an interactive command for you to enter queries, type a query to search the index press enter and you'll see the results.
