What does it do?
The Indexing component calls the Filtering component to extract the text and values from files that need to be filtered. After additional processing, it merges the resulting word lists into an index that is saved to disk. Indexing Service eventually merges content information (the text within a file) into the master index and saves value information (properties internal to the file) in the property cache. Source

The Change-Notification component informs Indexing Service when files have been altered (added, modified, deleted) to trigger indexing or re-indexing of the contents and values of changed files. Source.
