ElastAlert is a simple framework for alerting on anomalies, spikes, or other patterns of interest from data in Elasticsearch. ElastAlert works with all versions of Elasticsearch. If you have data being written into Elasticsearch in near real time and want to be alerted when that data matches certain patterns, ElastAlert is the tool for you. If you can see it in Kibana, ElastAlert can alert on it.

Searchkit is a tool allowing you can quickly build a search experience using predefined GraphQL resolvers and React components. Built on the top of Apollo GraphQL, React & Elasticsearch, Searchkit makes building a high-quality API a lot easier. The library provides GraphQL resolvers dedicated to handling the most common use cases you could think of when using filtering oriented API beginning with basic operations such as simple querying, ending on more tricky ones such as efficient facet filtering or pagination.

Qdrant ( quadrant ) is a vector similarity search engine. It provides a production-ready service with a convenient API to store, search, and manage points - vectors with an additional payload. Qdrant is tailored to extended filtering support. It makes it useful for all sorts of neural-network or semantic-based matching, faceted search, and other applications. With Qdrant, embeddings or neural network encoders can be turned into full-fledged applications for matching, searching, recommending, and much more.
 
The neural search uses semantic embeddings instead of keywords and works best with short texts. With Qdrant and a pre-trained neural network, you can build and deploy semantic neural search on your data in minutes.

Haystack is an end-to-end framework that enables you to build powerful and production-ready pipelines for different search use cases. Whether you want to perform Question Answering or semantic document search, you can use the State-of-the-Art NLP models in Haystack to provide unique search experiences and allow your users to query in natural language. Haystack is built in a modular fashion so that you can combine the best technology from other open-source projects like Huggingface's Transformers, Elasticsearch, or Milvus.
 
Haystack can perform semantic search and retrieve documents according to meaning, not keywords. It can ask questions in natural language and find granular answers in your documents. It can automate processes by automatically applying a list of questions to new documents and using the extracted answers.

Compose Transporter helps with database transformations from one store to another. It can also sync from one to another or several stores.Transporter allows the user to configure a number of data adaptors as sources or sinks. These can be databases, files or other resources. Data is read from the sources, converted into a message format, and then send down to the sink where the message is converted into a writable format for its destination. The user can also create data transformations in JavaScript which can sit between the source and sink and manipulate or filter the message flow.

The APM Server receives data from APM agents and transforms them into Elasticsearch documents. It does this by exposing an HTTP server endpoint to which agents stream the APM data they collect. After the APM Server has validated and processed events from the APM agents, the server transforms the data into Elasticsearch documents and stores them in corresponding Elasticsearch indices.

Official low-level client for Elasticsearch. Its goal is to provide common ground for all Elasticsearch-related code in PHP; because of this it tries to be opinion-free and very extendable.To maintain consistency across all the low-level clients (Ruby, Python, etc), clients accept simple associative arrays as parameters. All parameters, from the URI to the document body, are defined in the associative array.
