BETHESDA, Maryland, April 18, 2017 /PRNewswire/ -- A leader in enterprise and developer text retrieval software and document filters, dtSearch announces the release of new dtSearch product line versions with hash value support. (Hash values are unique numeric codes for forensic identification of files.) The new versions can generate hash values as part of the indexing process, and then append the hash values as searchable metadata, all without modification of the original files or their underlying hash values.
dtSearch products can index terabytes of data spanning multiple directories, emails and nested attachments, online data and other databases. Indexing and searching do not alter files or other data, and do not affect hash values. The V. 7.86 release can generate and search as metadata MD5 hash values. The V. 7.87 beta adds generation and searching of SHA-256 hashes. As with "normal" dtSearch indexing and searching, the new options do not alter underlying files and other data, or affect hash values.
The MD5/SHA-256 hash generation and searching options work with dtSearch Desktop with Spider and dtSearch Network with Spider for searching PC and network-based content. The hash options also apply to dtSearch Web with Spider for searching data across an Internet/Intranet site, and to dtSearch Publish for publishing data to portable media.
dtSearch's developer SDK product, the dtSearch Engine, has 64-bit and 32-bit .NET, C++ and Java APIs, with SDKs for Linux, Windows and UWP, along with Mac and Android in beta. The dtSearch Engine developer APIs include the new hash algorithm integration both as part of the indexing APIs and as part of the document filter APIs (for developers in need of data extraction, conversion and display without search).
General features across the dtSearch product line include:
Terabyte Indexer and Multithreaded Searching. dtSearch products can index over a terabyte of text in a single index. The index can cover multiple data sources, including different file directories, email stores with attachments, databases and other online data. dtSearch products can create and search any number of indexes, and can search indexes during updates. The products support efficient multithreaded searching, with no limit on the number of concurrent search threads.
25+ Search Options and International Language Support. The dtSearch product line has over 25 search types, including special forensics search options (like the ability to identify credit card numbers in data). For international languages, dtSearch products support Unicode, including support for right-to-left languages, and Chinese/Japanese/Korean character handling options.
Faceted Search and Other Data Classification Options. The dtSearch Engine SDK supports categorization based on document full-text contents, internal document metadata, database content, or data attributes associated with documents during document indexing. The dtSearch Engine also has APIs for faceted searching and other advanced data classification methods.
Document Filters and Supported Data Types. The product line uses dtSearch's own document filters to work with "Office" documents, PDF, compression formats, emails and multilayer nested attachments, online data and other databases. After a search, the document filters support the display of retrieved data with multicolor highlighted hits. (Document filters are both built into the product line and also available for separate licensing.)
Federated Searching and the dtSearch Spider. dtSearch products offer federated search across any number of databases, directories, email files and attachments. The dtSearch Spider adds local and remote online content to a search. The Spider can index sites to any level of depth, with support for public and secure online content. dtSearch products provide integrated relevancy ranking, including multicolor highlighted hits across both online and offline data.
