Elasticsearch can be configured to load trained ML

Another very useful feature for development is runtime_fields. Usually, the fields of an index should be declared before loading data into Elasticsearch, as we have done so far. Alternatively, fields can be added to an existing index, which is then updated to perform the defined analysis on the documents, until which the field cannot be used. runtime_fields allow a different approach: the value of the field is determined at runtime, i.e. when the data is already queried or analyzed. The value of the runtime_fields can be determined by providing a script via the search API or by adding it manually via Kibana.



runtime_fields are useful during development or for peripheral applications. Once it is determined that a field is useful for the use case under consideration, a decision must be made whether to keep the functionality encapsulated during runtime or convert it to a more permanent stored solution.

Finally, let's move on to something a little more unusual. As mentioned, plugins and extensions are also part of the Elastic Stack. OpenNLP is a machine learning (ML)-based framework for processing natural slovenia consumer email list text and can be used for various tasks, including named entity recognition (NER). models to analyze the text it reads. To do this, you first need to load the plugin and the required ML models into Elasticsearch and then define an ingest pipeline that enriches the text to be indexed with the desired annotations.
e in the Gitpod workspace mentioned above and the NER models can be tried out using the code described. As an example, here is the list of recognized people in the Wikipedia article on Michael Jordan:



This blog post shows how a search heuristic based on text analysis and query DSL can be implemented within Elasticsearch with minimal resources. Inputs can be made more error-tolerant using ngrams and phonetic transformation, and suggestions for search results can be provided while the user is entering data (i.e. when the search parameters are incomplete). Fuzzy Search and the combination of the developed search heuristics are used to design a multi-layered search that is both fast and error-tolerant.

1. You can simply use the linked repo template "elasticsearch-demo" to create your own repo on GitHub. Then use the link to your repo to create and open a workspace via the GitPod dashboard. The workspace setup will be done automatically for you and the code examples will work out-of-the-box. ↩
