inclusionPatterns
A list of glob patterns for documents that should be indexed. If a document that matches an inclusion pattern also matches an exclusion pattern, the document is not indexed.
Some examples are:
*.txt will include all text files in a directory (files with the extension .txt).
*/.txt will include all text files in a directory and its subdirectories.
tax will include all files in a directory that contain 'tax' in the file name, such as 'tax', 'taxes', 'income_tax'.
