The relevant problem of text analytics tools development is real-time mode establishment via data processing operations parallelizing. The use of the local parallel (LP) approach is advantageous. The classification of search algorithms for text blocks, which are candidate for local parallel (LP) approach implementation, was presented. The advantages of LP approach implementation were regarded. The variants of bit and segmental word-patterns processing in text block search tasks were proposed and exemplified. Perspectives and certain threats to its implementation were studied in terms of Boyer-Moore algorithm.
