Source Content

💾 The value to search within.

Supported formats:
  ✓ String: "hello world"
  ✓ Array: ["a", "b", "c"]
  ✓ Comma-separated string: "a,b,c"
  ✓ JSON-stringified array or object: '["a","b"]'

Search Terms

🔍 Search terms (one or more) to find within the data.

Supported formats:
  ✓ String: "hello world"
  ✓ Array: ["a", "b", "c"]
  ✓ Comma-separated string: "a,b,c"

Input Setup

Input Function (optional)

⚙️ Optional pre-processing function applied to the input before internal logic (e.g., convert object to string, normalize case). Internal transformations such as case handling will still apply afterward.

Result Handling

Output Function (optional)

⚙️ Optional function to apply to the result before returning it (e.g., str => str + ' €', val => val !== undefined for boolean conversion). Useful for chaining transformations on the output.

🎯 Using special value — click input to type instead

Test with:

Falsy undefined null "" empty 0 false NaN

Truthy true 42 "hello" {} empty [] empty {a:1} [1,2,3]

Search Terms array

🔗 Result Handling — Chain Variables

Chain apply-mode variables to the output. Each variable receives the result of the previous one.

/**
 * Checks if the source contains **all** of the provided search terms.
 *
 * @param {*} data.src - The data to search within (string, number, object, etc.).
 * @param {Array<string>|string} data.tms - Term, array or comma-separated string of terms to search for.
 * @param {string|Function} [data.out] - Output handler: function to transform result or string with format.
 *
 * Direct-mode specific parameters:
 * @param {Function} [data.pre] - Optional function to transform `src` before searching.
 *
 * @returns {boolean} True if all of the terms are found, false otherwise.
