 ## Search Index

Without an index every search would need to scan every page in your site which would quickly become very inefficient.
 
 ## Search engine
 
 The search engine takes a search query, runs it through the search index, and returns any matching documents.
 
 ## Visual component

 ## Use an open source search engine
 
 Using an open source search engine is always free and allows you to enable offline search for your site. Note that you need to be careful with offline search because the entire search index has to be brought into the client, which can affect the bundle size significantly.
 
-Open source libraries like [`elesticlunr`](https://www.npmjs.com/package/elasticlunr) or [`js-search`](https://github.com/bvaughn/js-search) can be used to enable search for your site.

-Note that doing so will require you to create a search index when your site is built. For `elesticlunr`, there is a plugin called [`gatsby-plugin-elasticlunr-search`](https://github.com/andrew-codes/gatsby-plugin-elasticlunr-search) that creates a search index automatically.

 For other libraries, you can use a combination of [`onCreateNode`](https://www.gatsbyjs.org/docs/node-apis/#onCreateNode), [`setFieldsOnGraphQLNodeType`](https://www.gatsbyjs.org/docs/node-apis/#setFieldsOnGraphQLNodeType) and [`sourceNodes`](https://www.gatsbyjs.org/docs/node-apis/#sourceNodes) from the Gatsby node API to create the search index and make it available in GraphQL. For more info on how to do this check out [`gatsby-plugin-elasticlunr-search`'s source code](https://github.com/andrew-codes/gatsby-plugin-elasticlunr-search/blob/master/src/gatsby-node.js#L88-L126).
