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.
- Mispellings and typos still provide relevant results.
- External scoring factor hooks exposed so contrib modules can give administrators options for scoring.
- 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.
- Works independently of core search.
- Block provides related content type results from url query.
- Ngram length is configurable.
- Content types may be exclude from results.
- Fuzzy highlighting of misspelled search terms.
A default server and index are created when the module is installed. Just add a Search Page or a View using the default fuzzy index, run cron to index your site, and you're ready to search.
- From the main Search API configuration page, create a server using the Fuzzy Search service class.
- Create an Index using the server you just created.
- Click the Workflow Tab.
- Enable "Complete entity view".
- Enable the following processors: Both Fuzzy search processors, Ignore case, HTML filter, and Tokenizer.
- Move the Fuzzy Search excerpt processor to the bottom of the list, and the Fuzzy Search search settings processor just above it.
- The default settings should be fine.
- You will need the Search Pages sub module or Views to provide a place to search your site.
- Go to the main Search API page,
- Click Search Pages, add a search page, and configure with the index you created above, multiple terms for query type, and view mode as themed as search results.
- For Views, make a new view using the default fuzzyseach index, add a page display and configure as desired.
- Run cron to index your content. Visit the path for your search page.
These settings should get the module up and running.
