4 min readIn Elixir, the "@" symbol is used as a sigil to define module attributes. Module attributes are key-value pairs that are stored at the module level and can be accessed throughout the module. These attributes are often used to store metadata about the module or to provide configuration options. The "@" symbol is typically followed by the name of the attribute, such as "@example", and then the value assigned to that attribute.

4 min readScoring Solr autosuggestions can be achieved by configuring the Solr suggester component to take into account various factors such as the popularity of a suggestion, how closely it matches the user's query, and any custom boosting rules set by the developer. By specifying these parameters in the Solr configuration, the suggester can return more relevant and accurate suggestions to the user based on their input.

3 min readIn Elixir, you can flatten a nested list using the List.flatten/1 function. This function takes a list as input and returns a new list with all nested lists flattened into a single list. You can simply call List.flatten(your_nested_list) to flatten a nested list in Elixir.[rating:4418d73d-f96d-4383-97bd-2aa68e7b6810]What is the performance difference between iterating and flattening in Elixir.

2 min readTo group facet.field in Solr, you need to specify the field names that you want to group together in the facet.query parameter. This allows you to get facet counts for multiple fields in a single request. Additionally, you can also use the facet.pivot parameter to group fields hierarchically, allowing for more complex faceting options. By specifying the desired facet fields in the facet.query or facet.

6 min readTo get the value of a JSON property in Elixir, you can use the Jason.decode!/1 function from the Jason library to parse the JSON string into an Elixir map. Once you have the JSON parsed into a map, you can access the value of a specific property by using the key of the property as a key to access the value in the map. For example, if you have a JSON object json containing a property named name, you can get the value of the name property by accessing json["name"].

5 min readTo write parameterized queries in Solr, you can use the Solr query syntax along with parameters. Parameters can be used to dynamically modify the query based on user input or other requirements.To use parameters in a Solr query, you can specify them using the "$" symbol followed by the parameter name. For example, if you have a parameter called "q", you can use it in the query as "$q".

6 min readTo implement Solr spell checker for compound words, you can follow these steps:Enable the SpellCheckComponent in your Solr configuration file by adding the following lines: truedefaulttruefalse5Define a custom spellcheck dictionary that includes compound words. You can do this by creating a text file with the compound words and their corrections, then adding it to the Solr configuration. Index your data with the compound words included, so that Solr can generate suggestions for them.
-
6 min readIn Elixir, you can run an infinite job or process by using a recursive function that calls itself indefinitely. You can achieve this by defining a function that performs the desired operations and then calls itself at the end to loop continuously. Make sure to include a condition that stops the recursion when needed to prevent the process from running indefinitely. This can be done by adding a base case or a termination condition within the function.

5 min readTo 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.

8 min readTo create a periodical timer in Elixir, you can utilize the Process.send_after/4 function in combination with a recursive function.First, define a function that will perform the desired action periodically. This function can use Process.send_after/4 to send a message to itself after a specified time interval. In the function, after performing the action, call the function recursively with the appropriate time interval.
