PHP SuperEzSearch: Search documents storing indexes in PHP structures

This package can search documents storing indexes in PHP structures.

It can create a search index for text document strings in PHP data structures stored in class variables.

The package can also search for given keywords and return the identifiers of the text documents indexed previously.

It can also return text documents related to given documents indexed by the package.

The search keyword may include negative work that should be excluded from the list of documents that the package returns as search results.

The database index can be saved by returning a string of data with the serialized version of the database index class variables so that the same index can be loaded by the package later.

The database index data can be in a binary format that may be compressed. It can also store the index data in session variables.
