Question

How can i search full text with sentence and search any word matched or different configuration

example:

it have to display result which matched the "proffessor john smith", "professor john" ", "proffesson smith"

Answer 1

There are lots of fulltext search technologies supports rails. elasticsearch and solar search ar eone of them

Rails cast about integrating solar search is here

Answer 2

There are some technologies compatible with rails. For example sunspot, as @scottxu wrote, or elasticsearch, as @knotito said. Good solution also - sphinx (fast and lite) and thinking_sphinx gem. If you use postgresql as database, and you do not want use external solutions - you can choose pg_search gem, that emplements fulltext search with pg technologies only. I prefer elasticsearch, but it requires JVM, and some people don't like this.

updated:

how to use pg_search: First, you should add pg_search to gemfile, make bundle install , and add to your model something like:

include PgSearch
pg_search_scope :search_by_title, :against => :title

if you didn't do it before.

After, you can try to test it in rails console: Professor.search_by_title('professor smith')

Answer 3

For fulltext searches you can use Elasticsearch

To implement that you can follow this railscast

Answer 4

you can use sunspot

description: Sunspot is a Ruby library for expressive, powerful interaction with the Solr search engine. Sunspot is built on top of the RSolr library, which provides a low-level interface for Solr interaction; Sunspot provides a simple, intuitive, expressive DSL backed by powerful features for indexing objects and searching for them.
