/**
* Cleans search query passed into Sphinx search engine, as follows:
* 1. Hyphenated words are replaced with keyword search for either the exact phrase with spaces
* or as a single word without spaces eg search for "know-it-all" becomes ("know it all"|"knowitall*")
* 2. Words with apostrophes are contracted eg "it's" becomes "its"
* 3. <, >, " and & are decoded from HTML entities.
* 4. Following special characters used as search operators in Sphinx are preserved when used with correct syntax:
* (a) quorum matching: "the world is a wonderful place"/3
* Finds 3 of the words within the phrase. Number must be between 1 and 9.
* (b) proximity search: "hello world"~10
* Finds hello and world within 10 words of each other. Number can be between 1 and 99.
* (c) strict word order: aaa << bbb << ccc
* Finds "aaa" only where it appears before "bbb" and only where "bbb" appears before "ccc".
* (d) exact match operator: if lemmatizer or stemming enabled,
* search will find exact match only and ignore other grammatical forms of the same word stem.
* eg. raining =cats and =dogs
* will not return "raining cat and dog"
* eg. ="search this exact phrase"
* will not return "searched this exact phrase", "searching these exact phrases".
* 5. Special characters /, ~, << and = not complying with the correct syntax
* and other reserved operators are escaped and searched literally.
* Special characters not explicitly listed in charset_table or blend_chars in sphinx.conf
* will not be indexed and keywords containing them will be ignored by Sphinx.
* By default, only $, %, & and @ characters are indexed and searchable.
* String transformation is in backend only and not visible to the end user
* nor reflected in the results page URL or keyword highlighting.
*
* @param string $search_string
* @return string
