Imagine if you could instantly search through millions of documents, products, locations and understand natural languages to find exactly what users need – that‘s the magic of search engines and Elasticsearch makes it possible by working with all kinds of data.
The Origins of Elasticsearch
Elasticsearch began as an effort to take the popular Lucene search library to the next level for real-time analysis and scalability…
Why Data Types Matter for Search Relevance
Searching relevant information is critical for digital experiences today. But the kind of data that needs to be searched vastly differs across text documents, products, geospatial coordinates, logs etc. This is where Elasticsearch data types come in…
Figure 1: Comparing properties of structured and unstructured data
Elasticsearch makes both kinds of data readily searchable through powerful abstractions like text, numbers, locations etc. Let‘s dive deeper into the main data types:
Text Type
The text datatype is most used for search experiences like full-text documents, email, articles etc. Here is how it handles analysis and indexing…
Numeric Types
From tracking prices and quantities in ecommerce to analyzing stock values – numeric datatypes like integers, floats enable precise numeric search…
Geo-Spatial Types
Combining latitudes and longitudes with types like shapes and polygons unlocks intelligent location-based search through geospatial types…
Real-World Applications
Leading internet companies rely on Elasticsearch data types to understand user intent and deliver relevant, personalized search results…
"mappings": {
"properties": {
"title": {
"type": "text"
},
"price": {
"type": "float"
},
"location": {
"type": "geo_point"
}
}
}
