Memory efficient fast keyword search library written in Kotlin based on ternary search trie data structure.

This library is ideal for memory constrained environments like Android. It is also fast and can be used for high performance applications.

An example app is provided in the app module. It is a simple app that searches for cities in the world based on a json file. Google maps is used to show the location of the city. You should provide your own Google maps API key in the local.properties file like below

```MAPS_API_KEY=YOUR_API_KEY```

• Prefix search
• Custom searchable object support
• Memory efficient
• Fast
• Case insensitive / case sensitive search

This library currently isn't hosted in any repository. You can download the source code and build it yourself.

    implementation project(path: ':keywordsearch')

provided you have library module in your project.

Create a class that implements the Searchable interface. The text field should return the text that you want to search on. For example

    data class City(val name: String, val country: String, val latitude: Double, val longitude: Double) : Searchable {
        override fun getSearchableText(): String {
            return name
        }
    }   

You can create a keyword search object to perform your searches on. You can create a keyword search object by passing a list of searchable objects to the constructor.

    val keywordSearch = KeywordSearch(caseSensitive = true) // case insensitive search

Note that the default configuration for caseSensitive is false. If you want to perform case sensitive search, you should pass true to the constructor.

You can add a searchable object to the keyword search object by calling the add method on the keyword search object.

    keywordSearch.add(city)

Your searchable object will be added to the keyword search object and will be available for search.

You can perform a keyword search by by calling the itemsWithKeyword method on the keyword search object. The itemsWithKeyword method returns a list of searchable objects that match the search query.

    val results = keywordSearch.itemsWithKeyword("lond")
