hook_search_preprocess

6 core.php hook_search_preprocess($text)
7 search.api.php hook_search_preprocess($text)

Preprocess text for search.

This hook is called to preprocess both the text added to the search index and the keywords users have submitted for searching.

Possible uses:

  • Adding spaces between words of Chinese or Japanese text.
  • Stemming words down to their root words to allow matches between, for instance, walk, walked, walking, and walks in searching.
  • Expanding abbreviations and acronymns that occur in text.

Parameters

$text: The text to preprocess. This is a single piece of plain text extracted from between two HTML tags or from the search query. It will not contain any HTML entities or HTML tags.

Return value

The text after preprocessing. Note that if your module decides not to alter the text, it should return the original text. Also, after preprocessing, words in the text should be separated by a space.
