Indexing and configuring search after the upgrade
To use the new search engine, reindexing and possible some new configuration is required.
About this task
If you are upgrading from a release before SDL Tridion 2011, then after you have upgraded, you must create a new index for the new search engine. If you expect to index items containing more than 10,000 words, you must also configure your maximum item size (and possibly the amount of memory allocated by the search engine).
Also, the new Lucene-based search engine, may result in different search results to your search queries than the old search engine. Specifically, operator precedence (in search queries such as a AND b OR c) is different in Lucene than in the old Verity search engine. You can work around the problem by using brackets to indicate precedence.
