Content Indexing
To provide for a successful search, Apache Solr for TYPO3 indexes your site's content.
The traditional way to index content in TYPO3 has been to index a page when it is being rendered. This approach has the drawback that new content is being indexed only when a visitor views the changed page. Depending on the amount of visitors and how often the changed page is viewed this can take a while.
In Apache Solr for TYPO3 we invented an Index Queue. The extension monitors any changes to the site's content. When an editor changes a page's content the page is added to the Index Queue and is indexed right away, making the new content searchable nearly instantly.
