First, install the plugin by invoking the command which fits your elasticsearch version (older versions can be found at the bottom): Elasticsearch versions 1.4.0 - 1.7.3:
bin/plugin --install analysis-hebrew --url https://bintray.com/artifact/download/synhershko/elasticsearch-analysis-hebrew/elasticsearch-analysis-hebrew-1.7.zip
You will need hebrew dictionary files. The open-sourced hspell files can be downloaded here: https://github.com/synhershko/HebMorph/tree/master/hspell-data-files. Next, Elasticsearch needs to be configured to load the dictionary from that folder: this is done by adding the following line to elasticsearch.yml file:
hebrew.dict.path: /PATH/TO/HSPELL/FOLDER
NOTE: as of elasticsearch 2.0, you have to place the dictionary files in a folder elasticsearch can easily access. A good place would be to stick it in the plugin folder: elasticsearch/plugins/elasticsearch-analysis-hebrew/hspell-data-files/
The easiest way to make sure the plugin is installed correctly is to request /_hebrew/check-word/בדיקה on your server (for example: browse to http://localhost:9200/_hebrew/check-word/בדיקה). If it loads, it means everything is set up and you are good to go.
Hebmorph is released open-sourced, alongside with hspell dictionary files. The Commercial option will grant you further support in making Hebrew search even better, and it comes with a proprietary dictionary. For more information, check out http://code972.com/hebmorph.
Use "hebrew" as analyzer name for fields containing Hebrew text
Query using "hebrew_query" or "hebrew_query_light" to enable exact matches support. "hebrew_exact" analyzer is available for query_string / match queries to be searched exact without lemma expansion.
Because Hebrew uses quote marks to mark acronyms, it is recommended to use the match family queries and not query_string. This is the official recommendation anyway. This plugin does not currently ship with a QueryParser implementation that can be used to power query_string queries.
