persistence.search.js

persistence.search.js is a light-weight extension of the persistence.js library that adds full-text search through a simple API.

Initialization:

persistence.search.config(persistence, persistence.store.websql.sqliteDialect);

Example usage:

var Note = persistence.define('Note', {
    name: "TEXT",
    text: "TEXT",
    status: "TEXT"
});
Note.textIndex('name');
Note.textIndex('text');

This sample defines a Note entity with three properties of which name and text are full-text indexed. For this a new database table will be created that stores the index.

Searching is done as follows:

Note.search("note").list(tx, function(results) {
  console.log(results);
});

or you can paginate your results using limit and skip (similar to limit and skip in QueryCollections).

Note.search("note").limit(10).skip(10).list(null, function(results) {
  console.log(results);
});

Query language

Queries can contain regular words. In addition the * wildcard can be used anywhere with a word. The property: notation can be used to search only a particular field. Examples:

• note
• name: note
• interesting
• inter*
• important essential

Note that currently a result is return when any word matches. Results are ranked by number of occurences of one of the words in the text.
