Talk to a mentorSame search, two engines: queries side by side
Index a products catalog and run a search — once in Elasticsearch, once in Solr.
# Elasticsearch: create index and query products # 1. Create index with explicit mappings PUT /products { "mappings": { "properties": { "title": { "type": "text" }, "brand": { "type": "keyword" }, "price": { "type": "integer" }, "description": { "type": "text" } } } } # 2. Search with full-text + facet + sort GET /products/_search { "query": { "multi_match": { "query": "wireless headphones", "fields": ["title^3", "description"] } }, "aggs": { "brands": { "terms": { "field": "brand" } } }, "sort": [{ "price": "asc" }] }
Elasticsearch uses a rich JSON Query DSL — full-text search, aggregations, sorting and highlighting all live in one request.
# Solr: schema and query for the same products index # 1. Schema (managed-schema) — explicit field types <field name="title" type="text_en" indexed="true" stored="true"/> <field name="brand" type="string" indexed="true" stored="true"/> <field name="price" type="pint" indexed="true" stored="true"/> <field name="description" type="text_en" indexed="true" stored="true"/> # 2. Query with full-text + facet + sort GET /solr/products/select ?q=title:(wireless headphones)^3 description:(wireless headphones) &facet=true &facet.field=brand &sort=price asc &wt=json
Solr uses HTTP query parameters with Lucene syntax; schema is explicit by default. Faceting and sorting are first-class.
# Both engines follow the same core indexing pipeline # 1. Source data (e.g. catalog export) cat products.ndjson | head -n 3 # 2. Bulk-index into Elasticsearch curl -s -X POST "http://localhost:9200/_bulk" \ -H "Content-Type: application/x-ndjson" \ --data-binary @products.ndjson # 3. Bulk-index into Solr curl -s "http://localhost:8983/solr/products/update" \ -H "Content-Type: application/json" \ --data-binary @products.json?commit=true # 4. Verify counts (both engines) curl -s "http://localhost:9200/products/_count" | jq .count curl -s "http://localhost:8983/solr/products/select?q=*:*&rows=0&wt=json" | jq .response.numFound # Same conceptual pipeline: analyze → index → replicate → query.
The indexing pipeline is conceptually identical in both engines — analyzers, inverted index, shards, replicas, then queries with faceting and relevance scoring.

Frequently asked questions: Elasticsearch vs Solr
Answers to what freshers and developers ask us most.
Which pays more in India in 2026: Elasticsearch or Solr?
Pay depends more on your role, search/data depth and the company than on the engine alone. Indicatively, developers working with Elasticsearch earn ₹4–8 LPA as freshers and ₹10–18 LPA at 2–4 years. Solr developers earn ₹4–7 LPA as freshers and ₹8–15 LPA at 2–4 years. Senior search engineers and platform architects can reach ₹20–40+ LPA. Elasticsearch skills are more in demand across product companies, observability and log analytics, so they often command a premium in India — but Solr experience remains valuable in enterprise search, e-commerce and public sector deployments.
Is Elasticsearch easier to learn than Solr for a beginner?
Yes, generally. Elasticsearch has a much larger learning ecosystem — more books, courses, blogs, YouTube tutorials and community help — and its REST API is intuitive. Solr is also REST-based but its configuration (solrconfig.xml, schema.xml) is more verbose, and there are far fewer beginner-friendly resources. Both are built on Apache Lucene, so the underlying concepts of indexing, analysis and querying transfer directly between them.
What is common between Elasticsearch and Solr?
Both are open-source search platforms built on Apache Lucene, so both use inverted indexes, tokenization, analyzers and relevance scoring. Both expose REST APIs, support faceted search, highlighting and geospatial queries, and both integrate with big data tools like Hadoop. In fact, Solr actually preceded Elasticsearch, and both borrow heavily from Lucene's internals — which is why moving between them is mostly a matter of learning configuration and operations.
Can I switch from Solr to Elasticsearch later in my career?
Yes, and it is a common move. Because both systems are built on Lucene, the core concepts — analyzers, mappings, queries, facets — transfer directly. Moving from Solr to Elasticsearch is mostly about learning Elasticsearch's REST DSL, its mapping conventions, and the wider Elastic Stack (Kibana, Logstash, Beats). A Solr developer can usually become productive in Elasticsearch within 3–6 weeks of hands-on work.
Which one should a fresher learn first for placements?
Start with Elasticsearch. It has far more job openings in India and is embedded in a broader stack (ELK — Elasticsearch, Logstash, Kibana — and the Elastic Observability and Security solutions). Elasticsearch skills appear in backend, data engineering, DevOps and security roles. Solr is still worth learning if you are targeting enterprise search, e-commerce or government projects — but it is a smaller and more specialised market.
Do I need to know Java to use Elasticsearch or Solr?
Not to start, but it helps. Both are Java applications, and their REST APIs mean you can work with them from Python, Node.js or curl without writing Java. However, custom analyzers, Lucene-level plugins and advanced tuning often require Java knowledge. Learning the REST API and JSON first is the fastest path — add Java later if you want deep customisation.
How long does it take to become job-ready in either search engine?
With regular practice, most learners need 3–5 months: indexing and analyzers, mappings, query DSL, facets, aggregations, relevance tuning, and 2–3 real search projects. For Elasticsearch, also learn Kibana, Logstash and basic cluster operations. Prior backend, database or data experience shortens the path significantly.
