| * 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. | |
