This project is read-only.


The basic full text index allows you to index items and search for them. Once an item has been added to the index, the text it is indexed against cannot be changed. Additionally items cannot be removed from an index once added.


The updatable full text index derives from FullTextIndex, adding in the following methods:
  • Remove
  • Reindex
These fill in the functional gaps in the FullTextIndex class.

UpdatableFullTextIndex is slightly more resource intensive than FullTextIndex, both in terms of processing when indexing items and general memory overhead. This is because it maintains a reverse-index of items against their associated nodes in the index. (FullTextIndex doesn't need this information as searching only ever traverses the nodes in the index.)
