To retrieve a paragraph search response from Solr, you can use the "hl" (highlighting) component in your query parameters. This component is used to specify the fields that you want to highlight in the search results. When highlighted fields are matched in the search results, Solr will return the relevant portion of the text (the paragraph) that contains the search terms.
To get paragraph search responses, you need to set the "hl" component in your query parameters to include the field(s) where you want Solr to search for and highlight the relevant text. Additionally, you can customize the parameters for highlighting, such as the number of characters to include before and after the highlighted text, as well as the format of the output.
Once you have configured the highlighting component in your query, Solr will return the search results with the highlighted paragraphs containing the matched terms. This allows you to quickly identify the relevant information in the search results and present it to the users in a concise and informative manner.

How to handle phrase queries for paragraphs in Solr search?
To handle phrase queries for paragraphs in Solr search, you can use the "field" query parser with the "qf" parameter to specify the field to search within and the "pf" parameter to specify the field to use for phrase matching.
For example, if you have a field called "content" containing paragraphs of text, you can configure your Solr query to search for a specific phrase within these paragraphs by using the following parameters:
1 2 3 |
q=content:"your phrase" qf=content pf=content |
This configuration tells Solr to search for the exact phrase within the "content" field and to prioritize results where the phrase appears in close proximity within the paragraph.
Additionally, you can use the "mm" parameter to control the minimum number of query terms that must match in order for a document to be considered a match. This can help ensure that the search results are relevant to the query.

|
mm=75%
|
By setting a high minimum match percentage, you can fine-tune the relevance of the search results based on the number of query terms that match in the document.
Overall, by configuring the query parser and parameters in your Solr search, you can effectively handle phrase queries for paragraphs and retrieve relevant search results.
What is the difference between standard search and paragraph search in Solr?
In Solr, standard search refers to the traditional keyword-based search where users input a query containing specific keywords or phrases to retrieve matching documents. The search results are typically ranked based on relevance to the query.
On the other hand, paragraph search in Solr involves searching for a specific paragraph or block of text within a document. This could be useful when users are looking for a particular section of a longer document or when they want to search within a specific context. Paragraph search allows for more precise and targeted search results, especially in cases where the user knows the exact passage they are looking for.
Overall, the main difference between standard search and paragraph search in Solr is the level of granularity and specificity in the search results. Standard search provides broader results based on keywords, while paragraph search allows users to search within specific paragraphs or blocks of text.
How to filter out irrelevant paragraphs in Solr search?
To filter out irrelevant paragraphs in Solr search, you can use query filters or facet filters to narrow down search results based on specific criteria. Here are some steps you can take to achieve this:
- Define a schema: Make sure your Solr schema includes fields that will help you identify irrelevant paragraphs, such as metadata fields or specific keywords.
- Use query filters: You can use query filters to exclude certain paragraphs based on specific conditions. For example, you can exclude paragraphs that contain certain words or phrases using the "NOT" operator in your query.
- Utilize facet filters: Facet filters allow you to further refine search results by applying additional filters based on specific criteria. You can use facet filters to exclude certain categories or classifications of paragraphs that are considered irrelevant.
- Implement boosting: You can also use boosting to give more weight to certain fields or criteria that are indicative of relevance. This can help boost the relevance of relevant paragraphs while downplaying irrelevant ones.
- Monitor and adjust: Regularly monitor search results and user feedback to identify and exclude irrelevant paragraphs. Make adjustments to your filters and boosting strategies as needed to improve the overall search experience.
By implementing these strategies, you can effectively filter out irrelevant paragraphs in Solr search and improve the relevance of search results for your users.
What is the purpose of scoring in paragraph search in Solr?
The purpose of scoring in paragraph search in Solr is to determine the relevance of a document or paragraph to a given query. This is done by assigning a score to each document or paragraph based on how well it matches the query terms and other relevance factors. The higher the score, the more relevant the document or paragraph is to the query. Scoring helps to rank search results in order of relevance, allowing users to quickly find the most relevant information.
