Elasticsearch Query Generator — Complete Guide
A complete guide to the Elasticsearch Query Generator: how it works, how to use it, real use cases, and tips for generating an Elasticsearch query DSL body…
The Elasticsearch Query Generator is a free, instant online tool for generating an Elasticsearch query DSL body for a common search pattern. This complete guide walks through what it does, how to use it, where it works best, practical tips, and answers to common questions — everything you need to get great results without any signup or installation.
What is the Elasticsearch Query Generator?
An Elasticsearch query generator gives you a correct query DSL body for a common search pattern so you can stop wrestling with nested JSON. Pick the pattern — a full-text match, a bool query combining must and filter clauses, a range filter, or a terms aggregation — and name the field, and it returns a structured JSON body for the _search endpoint. Search engineers use it to start a query, recall the difference between the scoring must clause and the cached filter clause, or build an aggregation. It runs in your browser and generates instantly. Paste the body into Kibana Dev Tools, replace the placeholder search terms and the example status filter, and adjust size and sort. Each template uses the right context — filters for exact matches and date ranges, must for relevance scoring — so your queries are both correct and fast on a real index.
How to use the Elasticsearch Query Generator
Getting a result takes only a few seconds:
- Pick the query pattern you need.
- Enter the field name to query.
- Click Generate to produce the query DSL.
- Paste it into Kibana Dev Tools and replace the placeholders.
You can open the Elasticsearch Query Generator and start generating right away. Because it runs instantly and for free, it costs nothing to generate several times and keep the result that fits best.
Common use cases
The Elasticsearch Query Generator suits a range of situations:
- Starting a full-text search query against an index
- Combining scoring must clauses with cached filter clauses
- Filtering documents by a date or numeric range
- Building a terms aggregation for a facet or report
- Recalling the Elasticsearch query DSL structure
Across all of these, the appeal is the same: a fast, repeatable result that would take far longer to put together by hand, available the moment you need it.
Tips for better results
- Keep exact matches in filter context so they get cached.
- Use date math like now-7d/d for rolling time windows.
- Set size to 0 when you only want aggregation results.
- Add explain to debug why a document scored the way it did.
Frequently asked questions
When should I use filter vs must
Put exact-match and range conditions in the filter clause — it skips relevance scoring and is cached, so it is faster. Use must for full-text conditions where the match score should influence ranking. Combining both in a bool query is the common pattern.
Why does the aggregation set size to 0
Setting size to 0 tells Elasticsearch you only want the aggregation buckets, not the matching documents. That avoids transferring hits you do not need and makes a facet or report query much lighter.
What are the now-7d expressions
They are Elasticsearch date math: now-7d/d means seven days ago rounded to the start of the day, and now/d means the start of today. They let you express rolling time windows without computing timestamps yourself.

Why use a elasticsearch query generator?
The appeal of a elasticsearch query generator is speed. It gives you correct, copy-paste-ready output in seconds, turning a task that would otherwise mean a blank page or manual effort into a quick, repeatable step you can run whenever you need it. It runs entirely in your browser, costs nothing, and never asks you to sign up, so you can generate again and again until a result fits — then take it into your own work and refine it from there. Because there is no cap on how many times you run it, the smart approach is to generate several options, compare them side by side, and keep the one that lands rather than settling for your first attempt.
Good to know
Is a elasticsearch query generator free to use?
Yes — a good elasticsearch query generator is completely free, with no usage caps and no account required. Generate as many results as you like; nothing is locked behind a paywall or a trial.
Do I need an account or any installation?
No. It runs right in your browser, so there is nothing to download and no account to create, and because everything happens locally your inputs stay on your own device.
Does it work on mobile devices?
Yes. The page is responsive and works on phones, tablets, and desktops, so you can generate a result wherever you happen to be.
