What is indexing

From text to lexemes

In this chapter I will explain what "indexing" is within a PostgreSQL full text search setting and how this module goes about creating such a "FTS index".

As said on the introduction page, a full text solution most convert your passages of text (field data in our case) into something else in order for it to perform full text searches. This "something else" in PostgreSQL is called a tsvector - a data type specially designed to hold processed lexemes.

What are lexemes?

PostgreSQL Full Text Search

This is the main (end-user) documentation for the PostgreSQL Full Text Search module, explaining how this module works, how to setup and manage your FTS indexes, how to manage your database indexes and how to use Views to leverage the power of full text within your Drupal installation.

Note: Since the module is still in early stages of development, consider these pages to shift as new features are added, bugs are fixed or simply functionality is optimized.

Before we dive into a hands-on approach, a bit of background:

Search Engine Optimization Modules

Drupal offers many features for search engine optimization. This document provides a list of features that are often used and a brief explanation of each.

Design for Low Bandwidth

Drupal offers a variety of tools and features to reduce bandwidth requirements, including:

Adaptive Images

Your site is being increasingly viewed on smaller, slower, low bandwidth devices. On those devices your desktop-centric images load slowly, cause interface lag, and cost you and your visitors un-necessary bandwidth and money. Drupal includes the functionality to deliver small images to small devices; reducing bandwidth and resource requirements.
