It depends on how the data is arranged. In case it is an array, use linear search or binary search or interpolation search according as the array is sorted or not and based on the distribution of data. If some other data structures are used (like heap) for making data retrieval efficient, other algorithms exist.
The average searching runtime for the keyword "algorithm" in a typical search engine is typically less than a second.
binary search system
The best search algorithm to use for a sorted array is the binary search algorithm.

The linear search algorithm is a special case of the brute force search.
These are terms given to the various scenarios which can be encountered by an algorithm. The best case scenario for an algorithm is the arrangement of data for which this algorithm performs best. Take a binary search for example. The best case scenario for this search is that the target value is at the very center of the data you're searching. So the best case time complexity for this would be O(1). The worst case scenario, on the other hand, describes the absolute worst set of input for a given algorithm. Let's look at a quicksort, which can perform terribly if you always choose the smallest or largest element of a sublist for the pivot value. This will cause quicksort to degenerate to O(n2). Discounting the best and worst cases, we usually want to look at the average performance of an algorithm. These are the cases for which the algorithm performs "normally."
In a binary search algorithm, typically log(n) comparisons are made when searching for a specific element in a sorted array, where n is the number of elements in the array.
RSA (Rivest, Shamir, and Adelman) is the best public key algorithm.
dijkstra's algorithm (note* there are different kinds of dijkstra's implementation) and growth graph algorithm
No, the complexity of searching in a database is typically not logarithmic. It is often linear or even higher, depending on the specific search algorithm and the size of the database.
To optimize your string searching algorithm for faster performance using the Knuth-Morris-Pratt (KMP) algorithm, focus on pre-processing the pattern to create a "failure function" table. This table helps skip unnecessary comparisons during the search, improving efficiency. Additionally, ensure efficient handling of edge cases and implement the KMP algorithm's pattern matching logic effectively to reduce time complexity.
