This is Nutrimatic (http://nutrimatic.org/usage.html). To build the source, run "./build.py". You will need the following installed: * Python * g++ * libxml2 (ubuntu: apt-get install libxml2-dev; osx: pip install lxml) * libtre (ubuntu: apt-get install libtre-dev; osx: brew install tre) To do anything useful, you will need to build an index from Wikipedia. 1. Download the latest Wikipedia database dump (this is a ~13GB file!): wget https://dumps.wikimedia.org/enwiki/latest/enwiki-latest-pages-articles.xml.bz2 2. Extract the text from the articles using Wikipedia Extractor (this generates ~12GB of text, and can take several hours!): # See http://medialab.di.unipi.it/wiki/Wikipedia_Extractor wget https://raw.githubusercontent.com/attardi/wikiextractor/master/WikiExtractor.py python WikiExtractor.py enwiki-latest-pages-articles.xml.bz2 This will write many files named text/??/wiki_??. 3. Index the text (this generates ~50GB of data, and can also take hours!): find text -type f | xargs cat | bin/make-index wikipedia This will write many files named wikipedia.?????.index. (You can break this up; run make-index several times with different sets of input files, replacing "wikipedia" with unique names each time.) 4. Merge the indexes; I normally do this in two stages: for x in 0 1 2 3 4 5 6 7 8 9 do bin/merge-indexes 2 wikipedia.????$x.index wiki-merged.$x.index done bin/merge-indexes 5 wiki-merged.*.index wiki-merged.index There's nothing magical about this appproach with 10 batches, you can use any way you like to merge the files. The 2 and 5 numbers are minimum phrase frequency cutoffs (how many times a string must occur to be included). 5. Enjoy your new index: bin/find-expr wiki-merged.index '<aciimnrttu>' If you want to set up the web interface, write a short shell wrapper that runs cgi-search.py with arguments pointing it at your binaries and data files, e.g.: #!/bin/sh export NUTRIMATIC_FIND_EXPR=/path/to/nutrimatic/bin/find-expr export NUTRIMATIC_INDEX=/path/to/nutrimatic/data/wiki-merged.index exec /path/to/nutrimatic/cgi-search.py Then arrange for your web server to invoke that shell wrapper as a CGI script.
