This repository contains data files used in Azure AI Search quickstarts, tutorials, and examples. Each folder represents a different sample data set. Most sample data is used for indexer and AI enrichment scenarios and is typically uploaded to Azure Storage so that it can be accessed by an indexer.

This repository also contains an ARCHIVE folder for previously published data files that are no longer used in samples or docs.

It previously included a STOPWORDS.MD file. This file is now in the Reference section of the Azure AI Search documentation. Stopwords reference (Microsoft analyzers) is the new location.

This folder contains 14 files of mixed content types, including HTML, JPG, PDF, PowerPoint, Word, PNG, and TXT files. These files are used to demonstrate the breadth of skillset processing of multiple content types using a combination of built-in skills. This sample data is intended for upload to an Azure Blob storage container, and then referenced from an indexer's data source object.

This folder contains three subfolders of clinical trials data from https://clinicaltrials.gov. Subfolders contain large and small numbers of files, plus a JSON version.

This folder includes PDF downloads of Wikipedia pages about well-known deserts across the world. These PDFs have text, images, tables, and other graphical elements.

This folder includes 4 PDF files of famous American speeches by Abraham Lincoln, John F. Kennedy, and Martin Luther King. These files are used to demonstrate entity recognition and custom entity lookup. The custom entity definition file that provides the lookup entities is located with the Postman collection.

Used in: Custom Entity Lookup skill (Postman collection)

This folder includes a CSV file containing 10,000 book titles.

PDFs containing fictitious health plan data for Northwind and Contoso.

The Hotels folder contains fictitious demo data for quickstarts, tutorials, and code examples. This is the default data set for many Azure AI Search samples. It consists of 50 hotels across the United States and includes data to support all query types, including geospatial filters. It is structured and sized to run on the free tier.

Hotels demo data is provided in multiple formats to support different consumption models. The data is identical regardless of how you load it. Data files are in JSON, but there are several versions depending on whether you are uploading it Azure Cosmos DB or pushing it to an index in Azure AI Search.

Use the following files to create the hotels sample on your search service:

• Hotels.postman_collection.json - Using Postman, import this collection to execute requests that create and populate the Hotels index using JSON documents.

• Hotels_IndexDefinition.JSON - A standalone JSON file containing just the index. This index definition is equivalent to the hosted index on azs-playground search service.

• HotelsData_toAzureSearch.JSON - A standalone JSON file containing documents for 50 hotels and related room information.

• HotelsData_toCosmosDB.JSON - JSON used to populate an Azure Cosmos DB with the Hotels sample data. This can be used as a data source for an indexer to pull data into the Hotels index.

This sample data set consists of 5 JSON documents containing structured JSON, used for evaluating or testing JSON blob indexing. Each file consists of hotel information, an address complex field, and a rooms complex collection. The blob indexer can detect and match this JSON structure through equivalent fields in a search index.

This is a SQL script that creates a database, a table, and inserts 12 rows of partial hotel information.

This folder contains two files:

• A CSV file provides data consisting of customer reviews of various fictional hotels in Europe. You can use this data in AI enrichment tutorials, applying sentiment analysis, language detection, and text translation. When indexing content from a CSV file, be sure to select a parsing mode so that individual documents can be created for each line in the file.

• A JSON file provides a skillset definition.

Content from NASA's earth book (February 2019) is used in conceptual examples that explain semantic search and answers. This folder contains a collection of PDFs from NASA's downloadable books site. The folder includes intact versions of the entire book as single PDF file. A subfolder contains per-page extractions as separate PDF files for both images and text, as well as text-only pages.

The first 10 PDFs in \azure-search-sample-data\nasa-e-book\text-only are used in entity recognition and entity linking skills processing demos.

Images from https://unsplash.com/s/photos/landmark and https://unsplash.com/s/photos/ are used in OCR and image analysis skills processing demos. There are ten images in each folder.

• The "jpg-landmarks" folder contains photos of well-known buildings and structures. It's used to demonstrate image analysis.

• The "jpg-signs" folder contains photos that include signs and is used to demonstrate OCR skillset processing.

Used in: Demo skills (Postman collections for OCR and Image Analysis)

This folder includes 10 Word document files in Spanish and French, five in each language. Content consists of museum descriptions from the "Essential Museums" brochure on the Official tourism portal of Spain. These files are used in Language Detection and Text Translation skills processing demos. Content from the brochure was copied into individual Word document files, one for each museum and language combination.

Used in: Demo skills (Postman collections for Text Translation and Language Detection)

The original version of the built-in sample containing fictitious hotel information.

An example that used data from the Caselaw has been updated to use different data and steps. The data file used for that exercise is now archived. The Caselaw Access Project provides public bulk downloads of case data by jurisdiction. Several jurisdictions are freely available without having to request access first. We chose the first one (Arkansas jurisdiction) and took the first 10 cases. The file name for this data set is caselaw-sample.json. If you upload this file to Azure Blob storage and use the Import data wizard to index the documents, choose the JSON Lines parsing mode.
