In my index (productsindex), I'd like to be able to query both the productname field and the brand field. Let’s go ahead and query something to see the result we get back: curl -XGET localthost:9092/movies/movies/_search I'm using the Completion Suggester in Elasticsearch to allow partial word matching queries. Let’s run the same query that we did a while ago to see if the suggestion results have changed.

> for index, movie in eval(name_year_list): > name_year_list =, movie.split('-')) for movie in movies] Our script to parse this file looks like: > import requests From a cursory look at the file, it looks like the second and third column in every row of the file are the name and the date of release.Įach line in the file looks something like 1682|Scream of Stone (Schrei aus Stein) (1991)|0||. For this, I am just going to loop through the u.item file from the dataset using a Python script. Now that we created a new movies index and a mapping for the movies index, lets go ahead and add data to the index. curl -XGET localhost:9200/movies/_mapping You can check if the index and mapping was created correctly by running the following command. For now, we will only be using the name of the movie and the year in which the movie was released as a part of our index mapping. Let’s go ahead and define a new mapping for the movies index. My problem is that this check introduced there only works if. Each index has one mapping type which determines how the document will be indexed.To use Completion Suggester, a special type of mapping field type called completion needs to be defined. Followup for 3977: if 3977 a check was added, that indexing completion suggester fields are rejected, if the weight is not an integer.

Defining a Mapping.Ī mapping in Elastic Search is a definition of how a document and its fields are stored. Within the dataset, I am going to be using the u.item file to seed my elastic search cluster with movie data.

This data set is publicly available for downloading here 'minimum_index_compatibility_version' : '5.0.0'įor this demo, I am going to build auto-complete suggestions on the ml-100k movie dataset. 'minimum_wire_compatibility_version' : '5.6.0', 'cluster_uuid' : '7QktTxXfSdSEhA5rnONpRw', We can verify that elastic search is running by running the following command curl -XGET localhost:9200 docker run -p 9200:9200 /elasticsearch/elasticsearch:6.0.1 Let’s start with spinning up elastic search. In-order to demo this, I am going to build an auto-complete field mapping on Elastic Search and then eventually build a golang web-service to act as an auto-complete API of sorts. The added advantage is the field can also have fuzziness and weights which means that it can adjust for typos and also re-sort suggestions based on factors that we can decide are more relevant to our use-case. CCirrusSearchMaintenanceSuggesterAnalysisConfigBuilder, Builds elasticsearch analysis config arrays for the completion suggester index CCirrusSearch. The completion suggester is a search-as-you-type field that is optimized for speed and returns results almost instantaneously. While there are many ways you can go about implementing auto-complete, I prefer using ES’s inbuilt completion suggester because it was built precisely for this use-case.

The completion_suggest field is the field we will use for the autocomplete function in the above code sample.Fast auto-complete can be a pretty big factor in content discovery and a strong implicit funnel to guide users and help them discover your catalog or content. In order to use completion feature, you need to dedicate one field, which will be called completion and you have to specify a special mapping for it.
