@ -285,6 +285,27 @@ The searched term is highlighted with an `<em>` tag by default.
Note: It is recommended to strip out all HTML tags and convert entities on the indexed content,
to avoid matching HTML attributes, and cluttering highlighted content with unparsed HTML.
### Adding Analyzers, Tokenizers and Token Filters
When a document is indexed, its individual fields are subject to the analyzing and tokenizing filters that can transform and normalize the data in the fields. For example — removing blank spaces, removing html code, stemming, removing a particular character and replacing it with another
(see [Solr Wiki](http://wiki.apache.org/solr/AnalyzersTokenizersTokenFilters)).
Example: Replace synonyms on indexing (e.g. "i-pad" with "iPad")
<?php
class MyIndex extends SolrIndex {
function init() {
$this->addClass('Page');
$this->addField('Content');
$this->addAnalyzer('Content', 'filter', array('class' => 'solr.SynonymFilterFactory'));
}
}
// Generates the following XML schema definition:
// <field name="Page_Content" ...>
// <filter class="solr.SynonymFilterFactory" synonyms="syn.txt" ignoreCase="true" expand="false"/>
// </field>
## Debugging
### Using the web admin interface
