The Blast is a full text search and indexing server written in Go that built on top of the Bleve. Blast server provides functions through gRPC (HTTP/2 + Protocol Buffers).
This repository includes Blast CLI that is a command line interface for controlling Blast server, and Blast REST server that provides a traditional RESTful API (HTTP/1.1 + JSON).
Blast makes it easy for programmers to develop search applications with advanced features.
- Full-text search and indexing
- Faceting
- Result highlighting
- Text analysis
For more detailed information, refer to the Bleve document.
The Blast server parameters are described in blast.yaml.

You can specify the index mapping describes how to your data model should be indexed. it contains all of the details about which fields your documents can contain, and how those fields should be dealt with when adding documents to the index, or when querying those fields. The example is following:

The blast command starts Blast server. You can display a help message by specifying -h or --help option.
$ ./bin/blast --config ./example/blast.yaml --index-mapping ./example/index_mapping.jsonThe get index command retrieves an index information about existing opened index. You can display a help message by specifying the - h or --help option.
$ ./bin/blastcli get index --include-index-mapping --include-index-type --include-kvstore --include-kvconfigThe result of the above get index command is:

}The put document command adds or updates a JSON formatted document in a specified index. You can display a help message by specifying the - h or --help option.
The document example is following:
$ ./bin/blastcli put document --resource ./example/document_1.jsonThe result of the above put document command is:
{
"put_count": 1
}The get document command retrieves a JSON formatted document on its id from a specified index. You can display a help message by specifying the - h or --help option.
$ ./bin/blastcli get document --id 1The result of the above get document command is:
