This library provides an object oriented way to programmatically build queries for the Amazon Cloud Search service. It's inspired by Doctrine's query builder. A query's __toString method will return a decoded string, as provided by the http_build_query function
##Installation
Add to your composer.json:
"require": {
    ...
    "brighttalk/acs-query-builder": "dev-master"
}
$query = $qb->searchByFieldValue("fieldName", "'fieldValue'")
    ->setSize(20)
    ->setStart(0)
    ->setRank('-fieldName')
    ->getQuery();
echo $query;would output bq=fieldName:'fieldValue'&start=0&size=20&rank=-fieldName (the "-" in the rank expression means it is in descending order - see the Amazon docs )
The supported expressions are: andX, orX, notX, eq
Example:
$query = $qb->setSearchExpression($qb->expr()->andx(
        $qb->expr()->eq("aFieldName", "'aFieldValue'"),
        $qb->expr()->notx($qb->expr()->eq("anotherFieldName", "'anotherFieldValue'"))
    ))
    ->setSize(20)
    ->setStart(0)
    ->getQuery();
echo $query;would output bq=(and afieldName:'afieldValue' (not anotherFieldName:'anotherFieldValue'))&start=0&size=20
