1. Keyword search: This is the most common type of search technique where users enter specific words or phrases related to their query into a search engine to find relevant results.
2. Boolean search: This technique involves using operators such as AND, OR, and NOT to combine or exclude keywords in order to refine search results.
3. Natural language search: Users can enter their query in the form of a question or sentence, and the search engine will attempt to understand the context and provide relevant results.
4. Advanced search: This technique allows users to use filters, date ranges, file types, and other advanced options to narrow down search results and find more specific information.
5. Image search: Users can search for images by entering keywords or uploading an image to find visually similar results.
6. Voice search: Users can use voice commands to search for information using virtual assistants like Siri, Google Assistant, or Alexa.
7. Semantic search: This technique uses artificial intelligence to understand the context and intent behind a search query, providing more relevant and accurate results.
8. Social media search: Users can search for information within social media platforms by using hashtags, keywords, or filters to find relevant posts, profiles, or discussions.

Linear Search (Sequential Search)
- Examines every element in the collection sequentially until the target element is found or the end of the collection is reached.
- Simple but can be inefficient for large collections.
Binary Search
- Divides the collection in half and compares the target element to the middle element.
- If the target is equal to the middle element, the search is complete.
- Otherwise, the half that does not contain the target is discarded and the search continues recursively on the other half.
- Requires a sorted collection.
Interpolation Search
- Similar to binary search, but uses a more advanced formula to estimate the index of the target element.
- Can be more efficient than binary search for large, evenly distributed collections.
Jump Search
- Divides the collection into equal subarrays and performs a linear search on each subarray.
- Can be more efficient than linear search for very large collections.
Hashing
- Creates a hash table that maps keys to indices.
- To search for an element, its key is hashed and the corresponding index is used to access the element in the table.
- Can be very fast, but requires additional memory for the hash table.
Tree-Based Search (e.g., Binary Search Tree, AVL Tree)
- Organizes the collection into a hierarchical tree structure.
- Each node in the tree contains a key and a reference to its children.
- The tree is traversed in a systematic way to locate the target element.
Graph-Based Search (e.g., Breadth-First Search, Depth-First Search)
- Represents the collection as a graph, where nodes represent elements and edges represent relationships.
- Traverses the graph in a structured manner to find the target element.
Specialized Search Techniques
- Backtracking: Used for solving problems with multiple possible solutions.
- Heuristic Search (e.g., A- Search): Uses heuristics to guide the search towards promising areas, often used in pathfinding and optimization problems.
- Genetic Algorithms: Evolutionary algorithms that simulate biological evolution to solve optimization problems.
