solr sanitizing query

Question

I am using solr with ruby on rails. It\'s all working well, I just need to know if there\'s any existing code to sanitize user input, like a query starting with ? or *

Answer 1

If you are using Solarium with PHP then you can use the Solarium_Escape::term() method.

/**
 * Escape a term
 *
 * A term is a single word.
 * All characters that have a special meaning in a Solr query are escaped.
 *
 * If you want to use the input as a phrase please use the {@link phrase()}
 * method, because a phrase requires much less escaping.\
 *

 *
 * @param string $input
 * @return string
 */
static public function term($input)
{
    $pattern = '/(\+|-|&&|\|\||!|\(|\)|\{|}|\[|]|\^|"|~|\*|\?|:|\\\)/';

    return preg_replace($pattern, '\\\$1', $input);
}
