Solr Search Queries

Searching for data using Solr search syntax

By enabling the advanced search feature, you can take advantage of Solr's flexible search syntax to analyze your data. For example, you can search for data that contains the terms 'Climate' and 'Financing' in close proximity to each other, or search for data or dates that fall within a specific range.

You can add Solr search queries by enabling 'Advanced search' under the search bar, then checking the 'Add query syntax to search' check box.

Enabling Solr search

Searching for keywords and search phrases

The following are examples of searches for a specific keyword or search phrase.

Task	Example	Syntax
Search for a keyword in a specific field	Search for the keyword AccessLog in the title field	title:AccessLog
Search for a phrase in a specific field	Search for the phrase Code 1918 in the title field	title:"Code 1918"
Search for a phrase in one field and a second phrase in another field	Search for Error 401 in the title field and Authorization is denied in the body field	title:"Error 401" AND body:"Authorization is denied"
Combine searches for multiple phrases or keywords using operators such as AND or OR	Search for Error 401 in the title field AND Authorization is denied in the body field, or search for Password in the title field.	(title:"Error 401" AND body:"Authorization is denied") OR title:Password
Search for a keyword in a specific field, excluding search results with another keyword in the same field	Search for 401 but not 404 in the title field	title:401 -title:404
Search for data in which a field does not contain a specific value	Search for data where the inStock field is not false	-inStock:false
Search for values in a specified range	Search for values from 20020101 to 20030101 in the mod_date field	mod_date:[20020101 TO 20030101]

Searching using wildcards

You can use the wildcard character (*) to search for results that are not exact matches. Solr search syntax does not support using a wildcard symbol as the first character of a search.

Task	Example	Syntax
Search for words starting with a string of characters	Search for any word that starts with En in the title field	title:En*
Search for words starting and ending with specific strings of characters	Search for any word that starts with En and ends with ed in the title field	title:En*ed
Search for values in a field that are less than or equal to a specified numeric value	Search for values in the code field that are less than or equal to 100	code:[* TO 100]
Search for values in a field that are greater than or equal to a specified numeric value	Search for values in the code field that are greater than or equal to 100	code:[100 TO *]
Search for data that contains a specific field	Find data that includes the message field	message:[* TO *]
Search for data that does not contain a specific field	Find data that does not have a message field	-message:[* TO *]

Searching using additional search options

You can search for terms that are a given number of words away from each other (called a proximity search).

Task	Example	Syntax
Search for keywords that are a specific number of words away from each other	Search for log analysis within 4 words from each other	"log analysis"~4
Search for transposed words	Search for log analysis or analysis log	"log analysis"~1

You can approximate a search for multiple keywords (for example, a search for business AND analysis) using a search with a large proximity value, such as "business analysis"~10000000. For practical purposes, this returns the same group of results as searching for business AND analysis. Unlike a search for business AND analysis, however, results in which business and analysis are closer together are regarded as having a higher search relevance. However, the proximity search also requires more time and system resources to perform.

You can determine which parts of a search query are treated as more important by providing a numeric boost factor. For example, the following query assigns higher importance to matches in the title field than matches in the body field: (title:MicroStrategy OR title:Analytics)^1.5 (body:Intelligence OR body:Server).

For a detailed overview of Solr query syntax, including information about creating queries that take advantage of functions, nested queries, boost factors, and more, see the official documentation for the query parser syntax. In most cases, Solr uses the standard Lucene query syntax to perform searches. For a list of exceptions, see the Solr wiki.
