Simple search engine

Overview

This repo contains simple implementation of search engine and includes

• Indexer
• Searcher

Package dependencies

You only need to have gradle locally.

OS X:

brew install gradle

Ubuntu:

sudo add-apt-repository ppa:cwchien/gradle
sudo apt-get update
sudo apt-get install gradle

Usage

Once you fetched the repo you should execute the command below. It should be performed only at the first build.

gradle wrapper

To run indexer you just have to execute one-line command

./gradlew runIndexer -PappArgs="['/path/to/data']"

The same thing for searcher. You can use standart boolean operators (not = '~', and = '&&', or = '||') and parenthesis

./gradlew runSearcher -PappArgs="['(~~true) && false && ~ (value || geographical)']"

Another option is to build an executable and run it afterwards (the same for Searcher and Indexer)

./gradlew buildSearcher 
./build/install/SearchEngineCourse/bin/SearchEngineCourse '(~~true) && false && ~ (value || geographical)'
