If you're working in the master branch, it will have it's own index which represents the tip view of content within that branch. Search indexes are maintained at a branch level. Cloud CMS essentially tries to extract as much as it can. For some formats, such as Audio and Video formats, header information is extracted whereas other formats (such as Powerpoint or PDF) will have its textual elements extracted. Depending on the MIME type, different elements are automatically extracted. Thus, all of your content is instantly available for full-text search.Ĭloud CMS supports a wide variety of desktop MIME type files, including Microsoft Office formats, PDF, text formats and most common Audio and Video formats. To do so, Cloud CMS performs text extraction on each binary file and loads the extracted tokens onto special fields within Elastic Search for discovery.

Cloud CMS will index the JSON fields first and then also index the PDF document and the Word document. This includes both its JSON structure and any binary attachments that belong to the node.įor example, a node might have 3 JSON metadata fields and 2 binary payloads (let's say, a PDF document and a Word document). Automatic Search IndexingĬloud CMS automatically indexes all of your content.

If you're looking for a reference on how to write search queries, we recommend visiting our page on Query Strings.

The Find API lets you execute concurrent MongoDB and Elastic Search queries and compose them into a single, intersecting record set. Thus, you can create as many branches as you would like and each branch will have a uniquely maintained and runtime-ready index to power your search API calls.Ĭloud CMS additionally offers the Find API. This allows you to execute simple searches as well as more complex queries that take into account term and phrase matching, nested operations, logical constructs, fuzziness, proximity, wildcards and regular expression matching.Ĭloud CMS automatically maintains Elastic Search indexes for you on a per-branch basis.

Under the hood, Cloud CMS uses Elastic Search and makes available to your editorial users and developers the full syntax of the Elastic Search Query DSL. This lets your editorial teams instantly search for content and find the things they're looking for. Any content you put into Cloud CMS is automatically indexed for full-text and structured search. We use the elasticsearch npm module to setup the connection to elasticsearch: import elasticsearch from 'elasticsearch' let client = new elasticsearch. Before we can index any documents, we have to create the index itself. The elasticsearch service is now running and ready to accept connections from node application code.

Volumes : - /var/data/elasticsearch :/usr/share/elastiscsearch/data Image : bryantebeek/elasticsearch -mapper -attachments :2.3.3 name : elasticsearch | docker | start/update elastiscsearch We can now provision our server with this docker image using ansible, and configure the volumes to ensure the indexes created by elasticsearch are persisted on the docker host disk. My colleague Bryan pushed it to dockerhub for anyone to use under the tag bryantebeek/elasticsearch-mapper-attachments:2.3.3.

FROM elasticsearch:2.3.3 RUN bin/plugin install mapper-attachments EXPOSE 9200 9300 ENTRYPOINT CMD The plaintext of the document is then used to create a document in elasticsearch.

The plugin takes care of transforming the documents into a plaintext format using apache tika. To accomodate this, elasticsearch has a plugin called elasticsearch-mapper-attachments.īecause we wanted to use a docker image to run elasticsearch, we decided to extend the elasticsearch:2.3.3 image and add the plugin on top of it. For this feature we needed to support PDF and office filetypes (doc, docx, pptx etc.) as well. Elasticsearch creates an index of documents based on metadata and their plain text content. In one of our recent meteor applications we included a full document search feature using elasticsearch.
