Szövegkeresésben

Szövegkeresésben is a Hungarian term that translates to "in text search" or "searching within text." It refers to the process of finding specific words, phrases, or patterns within a larger body of text. This is a fundamental operation in many areas of computing and information retrieval.

The simplest form of szövegkeresésben involves exact matching, where the search algorithm looks for an identical sequence of characters. More advanced methods can incorporate fuzzy matching, allowing for variations such as misspellings or grammatical differences. Regular expressions are a powerful tool used in szövegkeresésben to define complex search patterns that go beyond simple word matching.

Applications of szövegkeresésben are widespread. It is used in word processors for finding and replacing text, in web browsers for navigating documents, and in search engines for indexing and retrieving information from the internet. Database systems also rely on efficient text searching capabilities to query large datasets. The performance of szövegkeresésben algorithms is crucial, especially when dealing with very large texts or requiring rapid search results. Various algorithms, such as the Boyer-Moore algorithm or the Knuth-Morris-Pratt algorithm, have been developed to optimize this process.
