In Solr, stop words are commonly used to remove certain words from the search query that are too common and do not add much value to the search results. The stop words can be configured in the Solr Admin Console using the "Analysis" feature.
To configure stop words in Solr, you need to select the collection for which you want to configure stop words and modify the analyzer by adding the list of stop words that you want to use.
To configure stop words in Solr, you can follow these steps:
- Open the Solr Admin Console
- Select the collection for which you want to configure stop words
- Click on the "Analysis" link in the left sidebar
- In the "Field" dropdown, select the field for which you want to configure stop words
- In the "Analyzer" dropdown, select the analyzer that you want to modify (e.g. "StandardTokenizer")
- In the "Filter" section, click on "StopFilter" to expand it
- In the "Stop Words" field, add the list of stop words that you want to use, separated by commas (e.g. "a,an,the")
- Click on the "Save" button to apply your changes
Here's an example of a Solr query to search for documents containing the word "apple", but excluding documents that contain any of the stop words "a", "an", or "the":
SOLR Query Example :-
q=apple -a -an -the
Note that you need to prefix the stop words with a minus sign (-) to indicate that you want to exclude them from the search.
