Indexing and its components

Indexing deals with collecting data, cleaning, transforming and eventually
adding that data to the Solr index.

The extension currently supports two ways of indexing TYPO3 pages. The
initial goal was to create a solution in the sense of “Acts like Indexed
meaning that the same frontend indexing approach was used.

After releasing the public version it was decided to go an alternative way by
introducing an Indexing Queue that indexes pages on demand and offers
some more advantages over the frontend indexing approach.
