CLue - Command Line tool for Apache Lucene

Overview:

When working with Lucene, it is often useful to inspect an index.

Luke is awesome, but often times it is not feasible to inspect an index on a remote machine using a GUI. That's where Clue comes in. You can ssh into your production box and inspect your index using your favorite shell.

Another important feature for Clue is the ability to interact with other Unix commands via piping, e.g. grep, more etc.

Build a sample index to play with:

Clue bundles with some test data (15000 car data) for you to build a sample index to play with, do:

./bin/build_sample_index.sh my-idx

Examples:

Getting all the terms in the field 'color_indexed':

./bin/clue.sh my-idx terms color_indexed
Getting all the terms in the field 'color_indexed' starting with the term staring with 'r':

./bin/clue.sh my-idx terms color_indexed:r

./bin/clue.sh my-idx terms color_indexed | grep r
Do a search:

./bin/clue.sh my-idx search myquery
Get the index info:

./bin/clue.sh my-idx info
Iterate a posting for the term color_indexed:red

./bin/clue.sh my-idx postings color_indexed:red
List docvalues for the column-stride-field color:

./bin/clue.sh my-idx docval color
Get docvalue for the column-stride-field category for document 4:

./bin/clue.sh my-idx docval category 5
Get docvalue for the column-stride-field year of type numeric for document 3:

./bin/clue.sh my-idx docval year 3
Get docvalue for the column-stride-field json of type binary for document 3:

./bin/clue.sh my-idx docval json 3
Get docvalue for the column-stride-field tags of type sorted-set for document 3:

./bin/clue.sh my-idx docval tags 3
