Should use a simple analyser for the match query as that should prevent any unnecessary text splitting during the search phase.Ĭan also mention the fuzziness factor if the client is interested in getting autocomplete suggestions with fuzziness applied. analyser to be used for the search text.Clients should specifically use the match query as it has the provisions to explicitly provide, Step2 – Later when the end user actually starts typing on the text box in the user interface, the client application can trigger search queries in the background with the partial text available in the text box. The idea here is that these tokenised texts of the indexed field would serve as the future potential partial text entries from the user on the user interface. Ju, jur, jura, juras, jurass, pa, par, park. For example, an edge-ngram tokeniser of min length 2 and max length 6 would tokenise given the text “ jurassic park ” like below. How does an edge ngram token filter works?Īn edge ngram tokeniser will tokenise a given autocomplete text value into sub tokens of length ranging from a given min and max length parameters. store – option has to be enabled for the autocomplete field in the index definition to preserve the field contents intact within the FTS index so that this stored field value will be fetched explicitly during the query phase to perform the actual auto complete or suggestions for the user. It can also be chained with to_lower token filter if concerned about the case sensitivity. So during indexing, the autocomplete intended fields have to be analysed with a custom analyser making use of the edge-ngram token filter. Step1 – is to have the right FTS index definition for the fields that needs to be autocompleted. This approach involves the use of different index and query time analysers. Let’s explore a couple of functional approaches to implement the auto complete feature using Couchbase FTS. And It reduces the amount of character a user needs to type for getting the final search results, thereby enhancing the search experience of users. This helps in navigating or guiding a user by prompting them with likely completions and alternatives to the text as they are typing it. It is also known as Suggestions or Type Ahead or Search as you Type. For example, to use the filter, simple press cmd + F.“Autocomplete, or word completion, is a feature in which an application predicts the rest of a word a user is typing” Writing query is more efficient with a smart code completion feature, along with some of the best practices for SQL editor: Beautify SQL, Highlight Syntax, Split Results into Tabs, Split pane Horizontally that are all included in TablePlus.Įvery function in TablePlus is assigned to a shortcut key, which later you can customize, makes it quite handy for a lot of people.
