pecee/boolean-query-parser
==========================

[](#peceeboolean-query-parser)

Convert a boolean search query into a query that is compatible with a fulltext search.

### Notes

[](#notes)

This library is a maintained fork of the original project "BooleanSearchParser" created by DuncanOglethat, [available here](https://github.com/DuncanOgle/BooleanSearchParser).

The goal of this project is to iron out bugs, optimise the code, add new features and make it compatible with future versions of PHP.

Requirements
------------

[](#requirements)

- PHP 7.1 or higher

### Installation

[](#installation)

```
composer require pecee/boolean-query-parser

```

### Parsing a query

[](#parsing-a-query)

```
$parser = new \Pecee\BooleanQueryParser\BooleanQueryParser();

$formattedQuery = $parser->parse('ict OR (technology AND bob)');
```

**Output**

```
ict (+technology +bob)

```

### Order

[](#order)

Order and brackets are important, more often than not OR logic takes priority

`sales OR finance AND manager` will become `sales finance +manager` and not `sales +finance +manager`

Examples
--------

[](#examples)

InputOutput`ict``+ict``ict it``+ict +it``ict OR it``ict it``NOT ict``-ict``it NOT ict``+it -ict``web AND (ict OR it)``+web +(ict it)``ict OR (it AND web)``ict (+it +web)``ict NOT (ict AND it AND web)``+ict -(+ict +it +web)``php OR (NOT web NOT embedded ict OR it)``php (-web -embedded ict it)``(web OR embedded) (ict OR it)``+(web embedded) +(ict it)``develop AND (web OR (ict AND php))``+develop +(web (+ict +php))``"ict``null ``"ict OR it"``+"ict OR it"`Advanced examples
