Search Index Build Workflow

Build a full-text search index using Elasticsearch or Meilisearch with proper mapping, analyzers, and relevance tuning.

intermediate~75 minsearchindexworkflow

Objective

Create a searchable index of application data with good relevance for user queries.

Environment

A search engine
Source data to index
A search relevance test set

Steps

1. Define mapping

Create an index mapping with appropriate field types and analyzers.

Expected state: An index mapping is defined and created.

2. Import data

Bulk import source data into the search index.

Expected state: All source data is indexed and searchable.

3. Configure analyzers

Set up language analyzers, stemming, and stop word removal for the text fields.

Expected state: Text fields use appropriate language analyzers.

4. Tune relevance

Adjust field weights, boosting, and fuzziness to improve search results.

Expected state: Search results match the expected relevance for the test set.

5. Test search quality

Run the test set queries and compare results against expected matches.

Expected state: Search results meet the defined relevance threshold.

Decision points

Elasticsearch or Meilisearch?

Elasticsearch for complex needs
Meilisearch for simplicity

Use Meilisearch for simple, fast search; Elasticsearch for complex querying and aggregation needs.

Expected outcome

A search index is built with proper mapping and analyzers, and search quality is verified against a test set.

Verification

Run test queries and confirm the top results match expected documents; measure search latency.

Cleanup

Delete the index if testing is complete and it is not needed for production.

Good search is about relevance

Building the index is easy; making results relevant is hard. Test with real queries and iterate on analyzer and boosting configuration.

Implementation Notes

This workflow provides a structured approach to ensure consistent results across team members and environments.

Common Pitfalls

Skipping verification steps or rushing through the process can lead to incomplete results. Always follow each step in order and verify before proceeding.
