In Solr, you can match subdomains by using wildcards in your query. For example, if you want to search for documents on subdomain.example.com, you can use the query "subdomain:example.com". This will match any subdomain that ends with "example.com". You can also use regular expressions to match specific patterns in subdomains. For example, if you want to match subdomains that start with "abc", you can use the query "subdomain:/^abc..$/". This will match subdomains like "abc.example.com", "abcdef.example.com", and so on. By using wildcards and regular expressions in your Solr queries, you can easily match subdomains and retrieve relevant documents from your index.

How to properly format subdomains in a Solr query?
To properly format subdomains in a Solr query, you can use the field name and value syntax.
For example, if you have a field in your Solr index called "subdomain" and you want to search for a specific subdomain, you can format your query like this:
1
|
subdomain:example.com
|
This will search for documents in the "subdomain" field that contain the value "example.com".
You can also use wildcards to search for subdomains that match a certain pattern. For example, if you want to search for all subdomains ending in ".com", you can use the following query:
1
|
subdomain:*\.com
|
This will match any subdomain in the "subdomain" field that ends with ".com".
Overall, the key is to use the correct field name and value syntax in your Solr queries to properly format and search for subdomains.
How to configure Solr to handle internationalized subdomains in search queries?
To configure Solr to handle internationalized subdomains in search queries, you can follow these steps:
- Set up a new Solr core or collection for each subdomain. This will help organize the data for each subdomain separately and make it easier to handle internationalization.
- Configure the Solr schema to support international characters by using appropriate field types for storing text data, such as text_general or text_en for English text, and text_ for other languages.
- Use the Solr RequestHandler to route search queries based on the subdomain. You can create a custom RequestHandler that parses the search query and determines which Solr core or collection to query based on the subdomain in the request.
- Configure Solr to support language-specific analyzers for text processing. This will help improve the quality of search results for different languages by tokenizing and stemming text appropriately for each language.
- Set up language-specific stopwords and synonyms for each subdomain to customize the search experience for users in different languages.
- Test the configuration by performing search queries using different subdomains and languages to ensure that Solr is handling internationalized subdomains correctly.
By following these steps, you can configure Solr to handle internationalized subdomains in search queries effectively and provide a seamless search experience for users in different languages.
What is the impact of subdomains on search relevance in Solr?
Subdomains can impact search relevance in Solr in a few ways:
- Content segmentation: Subdomains allow you to segment your content into different sections based on the topic or category. This can help improve search relevance by ensuring that search results are more targeted and specific to what the user is looking for.
- Domain authority: Subdomains can also impact search relevance by affecting the overall domain authority of your website. If you have multiple subdomains that are all related to the same topic or industry, it can help establish your website as an authority in that niche. This can lead to higher search rankings and improved relevance for related search queries.
- Duplicate content: On the other hand, having multiple subdomains with similar or duplicate content can have a negative impact on search relevance. Search engines like Google may see this as duplicate content and penalize your website by lowering its search rankings. It is important to ensure that each subdomain has unique and valuable content to avoid any negative impact on search relevance.
Overall, the impact of subdomains on search relevance in Solr can vary depending on how they are implemented and the quality of content on each subdomain. Properly utilizing subdomains to segment and organize your content can help improve search relevance and enhance the overall user experience.
How to customize Solr to prioritize subdomains in search results?
To prioritize subdomains in Solr search results, you can use the "boost" query parameter to give more weight to documents from certain subdomains. Here's how you can customize Solr to prioritize subdomains in search results:
- Define a custom field in your Solr schema to store the subdomain information. For example, you can define a field called "subdomain" and set it as a string field type.
- Update your Solr index to include the subdomain information for each document. This can be done by extracting the subdomain information from the document URL and storing it in the "subdomain" field.
- Use the "boost" parameter in your Solr query to give more weight to documents from certain subdomains. You can specify the boost value for each subdomain in your query, for example:
1
|
q=keywords&bf=if(subdomain:example.com,2,1)
|
In this example, documents from the subdomain "example.com" will be given a boost value of 2, while all other documents will receive a boost value of 1.
- Reindex your Solr data to apply the changes to the search results.
By following these steps, you can customize Solr to prioritize subdomains in search results based on your specific requirements.
