8 min readTo create a relevant autocomplete in Solr, you need to start by configuring the autocomplete feature in your Solr schema. This involves defining a field for the autocomplete data and setting up the appropriate analyzers and tokenizers to enhance relevancy.Next, you will need to populate the autocomplete field with relevant data from your Solr index. This could include terms from various fields in your documents or specific terms that users commonly search for.

5 min readIn Elixir, you can find default user directories by using the System.user_home/0 function. This function returns the path to the current user's home directory. Additionally, you can use the System.user_data_dir/1 function to get the path to the user's data directory, and the System.user_cache_dir/1 function to get the path to the user's cache directory. These functions provide a convenient way to access default user directories in Elixir for reading and writing files.

7 min readTo speed up multiple filter queries in Apache Solr, there are a few strategies you can use. One approach is to optimize your index by using appropriate field types and configuring them with the correct parameters. This can help improve the performance of filter queries. Additionally, you can consider using the filter cache feature in Solr, which stores the results of filter queries in memory for faster retrieval.
-
8 min readIn Elixir, you can list the callers of a function by using the :erlang.process_info/1 function and the :current_stacktrace option. This will give you a list of information about the process, including the function calls that led to the current state. By filtering this information, you can identify the callers of a specific function. This can be useful for debugging and understanding the flow of the program.

6 min readTo debug Solr indexing, you can start by checking if the data is being properly sent to Solr for indexing. Review the indexing configuration and make sure that the fields and data types are properly defined.You can also check the Solr logs for any errors or warnings related to indexing. Look for any exceptions or stack traces that may indicate issues with the indexing process.
-
7 min readIn Elixir, you can validate input by using the case statement to match the input against specific conditions. This allows you to check if the input meets certain criteria and handle the validation accordingly. You can use pattern matching to define the conditions that the input must meet, and return an appropriate response based on whether the input is valid or not.

5 min readIn Solr, stemmed text can be stored and retrieved by using the "text_general" or "text_en" field types. When configuring the schema.xml file for Solr, make sure to define a field with one of these types for storing stemmed text.To store stemmed text in Solr, the text should be analyzed and indexed during the indexing process. This can be achieved by using the appropriate text analyzer for stemming in the field definition.
-
7 min readIn Elixir, you can check for a valid guard expression by using the defguard macro, which allows you to define custom guards. These custom guards can be used in the when clause of a function definition to enforce certain conditions on the input parameters.To create a valid guard expression, you need to define a guard function using the defguard macro and then use it in the when clause of a function definition.
-
5 min readTo include computed data in the Solr query response, you can use the "fl" parameter in the Solr query to specify the fields that you want to retrieve from the documents in the search result.You can use field references and functions in the "fl" parameter to compute new fields in the query response. For example, you can use a function like "sum(field1, field2)" to compute the sum of two fields in the response.

2 min readThe "?" operator in Elixir is commonly used as the "is" operator. It is used to check if a given expression meets certain conditions and returns either true or false. The "?" operator is typically paired with ":" to create a ternary expression, allowing for concise conditional logic in Elixir code.[rating:4418d73d-f96d-4383-97bd-2aa68e7b6810]What does the "?" operator evaluate in Elixir?In Elixir, the ".

8 min readAfter the finishing delta-import on Solr, you can execute a query to fetch updated information or data from the Solr index. You can use Solr's query syntax to specify the criteria for the information you want to retrieve. This query can be sent to the Solr server using HTTP requests or through the Solr client libraries in various programming languages.
