Information Retrieval demonstration

This project is a working demonstration of what I have learned in my second year information retrieval module. It features an indexer and a searching utility with its own query selector syntax.

The project is written in PHP 5.3, but parts will be re-written in more suitable languages later (either all Python or the front-end might stay as PHP - undecided yet).

Example usage

Indexing documents

# Index all documents under /documents
# Titles will be the filename
./indexer.php
# Index a specific document, relative to the directory you are calling from
./indexer.php document.txt
# Todo: supply attributes alternatively
#./indexer.php document.txt title:"Alternative title" attribute:value

Searching documents

# Search for a basic term
./search.php information
# Search for multiple terms (contains "information" or "retrieval")
./search.php information retrieval
# Todo: search for phrases
#./search.php "information retrieval"
# Todo: term weighting
#./search.php +information -retrieval
