\#Sequin#

N.B. This GitHub-hosted version of Sequin supercedes the one still available on SourceForge (), the original.

Sequin is a simple PHP library for building query-strings for Lucene-based search engines (e.g. Solr).

Query-strings are assembled using the fluent interface exposed by Sequin's `Query` class. An instance of `Query` comprises one or more `Term` objects, each of which may be a subquery—and each of those may also be further subdivided.

\##Requirements##

Sequin requires PHP version 5.3 or later; it uses no third-party libraries.

\##Installation (via Composer)##

Include the following in your `composer.json` file:

```
require:
{
    ...
    'danbettles/sequin': 'dev-master'
}

```

Then, run `composer.phar update`

\##Installation (manual)##

1. Download/clone the library.
2. Import the code into your application by `include`ing `src/boot.php`.

\##Usage##

The following—only slightly contrived—example demonstrates a good selection of Sequin's features. Here we build a query-string to search for soundtracks by Thomas Newman in the index of an imaginary online music retailer.

```
require_once 'path/to/sequin/src/boot.php';

$oQuery = Sequin\Query::newInstance('"Thomas Newman"')
    ->andTerm('soundtrack', null, 3)
    ->andQuery('music', 'dept')
        ->orTerm('film')
    ->endQuery()
    ->notTerm('"Erin Brockovich"');

print $oQuery;  // => "Thomas Newman" AND soundtrack^3 AND dept:(music OR film) NOT "Erin Brockovich"

```
