Jsearch – Contacts and Person Info Search in JSON File

Introduction to Jsearch - Contacts and Person Info Search

Jsearch is an open-source JSON-based search engine for managing and searching data. It allows users to create, read, update, and delete (CRUD) operations on their data, which can be stored in various formats such as JSON files. In this tutorial, we will explore how to use Jsearch to create a contacts and person info search functionality in a JSON file.

Setting up Jsearch

Before we dive into the tutorial, make sure you have Jsearch installed on your machine. You can download the Jsearch jar file from the official Jsearch website and follow the installation instructions.

Once Jsearch is installed, create a new folder for your project and add the Jsearch jar file to the folder. Create a new JSON file, for example, "contacts.json", and add some sample data to it. For this tutorial, we'll add the following contacts data:

{
  "contacts": [
    {
      "name": "John Doe",
      "email": "johndoe@example.com",
      "phone": "123-456-7890"
    },
    {
      "name": "Jane Smith",
      "email": "janesmith@example.com",
      "phone": "987-654-3210"
    },
    {
      "name": "Bob Brown",
      "email": "bobbrown@example.com",
      "phone": "555-555-5555"
    }
  ]
}

Creating a Contacts and Person Info Search in Jsearch

To create a contacts and person info search in Jsearch, follow these steps:

Step 1: Create an Index

First, we need to create an index for our JSON file using Jsearch. To do this, we'll use the jsearch command with the createindex option. Replace <indexname> with a desired name for your index.

java -jar jsearch.jar createindex --indexName <indexname> --jsonfile contacts.json

This command creates a new index with the specified name and imports the data from the "contacts.json" file into the index.

Step 2: Query the Index

Now that our index is created, we can query it using the jsearch command with the search option. For example, to search for all contacts whose name contains the word "Doe", use the following command:

java -jar jsearch.jar search --indexName <indexname> --query "name:*Doe*"

This command will return all contacts whose name contains the word "Doe".

Step 3: Customize the Search Results

We can customize the search results by adding more parameters to the search command. For example, to sort the search results by name in descending order, use the following command:

java -jar jsearch.jar search --indexName <indexname> --query "name:*Doe*" --sortField name --sortOrder desc

This command will return all contacts whose name contains the word "Doe" in descending order by name.

Step 4: Filtering Search Results

We can also filter the search results using the search command with the filter option. For example, to return only contacts with email addresses, use the following command:

java -jar jsearch.jar search --indexName <indexname> --query "name:*Doe*" --filter "email:*"

This command will return all contacts whose name contains the word "Doe" and have an email address.

Conclusion

In this tutorial, we learned how to use Jsearch to create a contacts and person info search functionality in a JSON file. We covered how to create an index, query the index, customize the search results, and filter the search results using the jsearch command. With these steps, you can create a powerful and scalable search engine for managing and searching your data.
