This module enables the jsMath script for displaying mathematical expressions. Users can enter arbitrary mathematical expressions in their drupal content by using the standard TeX syntax, including LaTeX and AMSLaTeX. jsMath renders this on the client's browser when the page gets displayed.
This module provides drupal sites with a fuzzy search engine to allow for broader keyword matches including partial or misspelled keywords.
Fuzzy matching is implemented by using ngrams. Each word in a node is split into 3 (default) letter lengths, so 'apple' gets indexed with 3 smaller strings 'app', 'ppl', 'ple'. The effect of this is that as long as your search matches X percentage (administerable in the admin settings) of the word the node will be pulled up in the results.
Features:
Mispellings and typos still provide relevant results.
Reindex function available to allow modules to specifically call a certain node for reindexing at next cron run.
Indexing of CCK textfield field types and taxonomy terms.
Implements hook_nodeapi's 'update index' op, so current modules integrating with core search will work the same.
