Changes:

• Now indexing misspelled word versions for fast lookup
• Indexed search for partial words
• Add “:” to break characters
• Check minimum_length and stopword list when adding to index, to keep it smaller
• Add clear_data() procedure
• Increase points given to link target when both source and target are in the search results
• Give points for query keywords making up a high percentage of content (”foo bar zig” wins over “foo bar zig zag” in a search for “foo bar”)
• Give points for keywords earlier in the query (”zig” wins over “zag” in a search for “zig zag”)
• Add unit tests
