4 min readTo disable Solr query analysis, you can modify the Solr configuration file to remove the filters or tokenizers that are being used in the query analysis process. By removing these components from the configuration, you can bypass the query analysis stage and perform a raw search on the indexed data.Additionally, you can also adjust the schema file to disable certain fields from being analyzed during the query process.

4 min readIn Solr, having a one-way synonym means that you can define a relationship between two words where one word is considered the synonym of the other, but not vice versa. This means that when one word is searched for, the synonym will also be considered in the search results, but not the other way around.To set up a one-way synonym in Solr, you can use the SynonymFilterFactory in your schema.xml file.

7 min readTo properly make Solr backups, you need to ensure that you have a consistent and reliable backup strategy in place. This includes scheduling regular backups, ensuring that backups are stored securely, and testing your backups to ensure that they can be restored successfully in case of a failure.Additionally, you should consider using tools like Solr’s built-in backup and restore functionality, or third-party tools like Solr Replication or snapshot-based backups.
-
6 min readIn Solr, searching across multiple indexes can be done by specifying the core names of the indexes that you want to search in the q parameter of the search request. By separating the core names with a comma, you can search in multiple indexes simultaneously. This allows you to query data from different sources and retrieve results that meet your search criteria across all specified indexes.
-
8 min readTo index a JSON file with nested arrays in Solr, you need to define a schema that can effectively represent the nested structure of the JSON data. This involves creating fields in the schema that can store the nested arrays as well as defining suitable field types for these fields.Once you have defined your schema, you can use Solr's DataImportHandler to import the JSON data into your Solr instance.
-
6 min readTo connect to a Solr node using Scala, you can use the SolrJ library which provides a Java client for interacting with Solr. You can add the SolrJ dependency to your Scala project using either Maven or SBT.Once you have added the SolrJ dependency, you can create a SolrClient object in your Scala code to connect to the Solr node. You will need to specify the URL of the Solr server when creating the SolrClient object.
-
5 min readTo index existing documents in Java with Solr, you can use the SolrJ library which provides APIs for interacting with Solr. First, you need to create a SolrClient object by providing the URL of your Solr server. Next, you can create a SolrInputDocument object for each document that you want to index. You can set the fields of the document using the setField() method. After creating the document objects, you can add them to Solr using the add() method of the SolrClient object.
-
6 min readTo search in XML using Solr, you first need to index the XML data in Solr. This involves converting the XML data into a format that Solr can understand, such as JSON or CSV, and then using the Solr API to upload the data into a Solr index.Once the XML data is indexed in Solr, you can perform searches using the Solr query syntax. This syntax allows you to search for specific keywords or phrases within the XML data, as well as to apply filters and sorting to the search results.
-
6 min readSolr uses a number of techniques to index files, including tokenization, text analysis, and document parsing.Tokenization is the process of breaking a document down into individual words or terms, which are then stored in the index. The text analysis process involves applying various filters and analyzers to the tokens to normalize them and improve search results.
-
5 min readTo match 1000gm to 1kg in Solr, you can create a conversion factor in your data processing pipeline that converts grams to kilograms. This can be achieved by either multiplying the gram value by 0.001 or dividing by 1000. Once the conversion is done, you can then index the data in Solr with the appropriate unit (grams or kilograms) so that searches for 1kg would also return results for 1000gm.
-
5 min readIn Solr, reducing the length of a multivalued field can be achieved by using the CopyField feature to create a new field with a limited length.First, create a new field in the schema.xml file with the desired maximum length. Then, use the CopyField command to copy the multivalued field values to the new field.
