jElasticlunr is a Java full text-search library. It is a Java port of the elasticlunr Javascript library.

Usage

A very simple search index can be created using the following code:

      Index index = ElasticLunr.createIndex();
      index.addField("title");
      index.addField("body");

Adding documents to the index is as simple as:

      JSONObject doc1 = new JSONObject();
      doc1.put("id", 1);
      doc1.put("title", "Oracle released its latest database Oracle 12g");
      doc1.put("body", "Yestaday Oracle has released its new database Oracle 12g.");
      ...
      index.addDoc(doc1);

Searching is simple:

      List<JSONObject> results = index.search("Oracle database");

      JSONObject result = results.get(0);
      String ref = result.getString("ref");

Format compatibility

The JSON format of the index is compatible with the format used in the elasticlunr Javascript library, so for example you can save the index as JSON in Java and load the same index in Javascript.
