dtSearch full changelog

JSON file format support:
Added support for indexing and searching JSON files (type id it_JsonRecord=371). As with XML, field searching, including nested field searching, is supported. Because JSON files cannot be automatically detected, the file type table must contain a rule identifying JSON files using a filename pattern (i.e., *.json).
JSON tables support:
If the file type table specifies the file type "JSON Table" (it_JsonTable=372), then the JSON file must consist of an array of objects, each of which will be indexed as a row of the file. Information outside the array object will be ignored.
CSV and JSON table configuration files:
Table configuration files provide a way to make indexed table data more useful by providing a way to specify the name and date for each row using data in the table. To enable table configuration files, set the flag dtsFlagUseJsonConfigFiles in Options.OtherFlags. When this flag is enabled and a CSV or JSON table is being indexed, dtSearch will look for a file named {filename}.config.json (where {filename} is the name of the CSV or JSON table) containing the rules to apply to that file. The .config.json file can contain these settings:
"RowName": A template using %% around field names specifying how to build an informative filename for each row. Example: "Row for %%lastname%% %%firstname%%". The row name will always include the ordinal and offset for the row data so the generated filename does not have to be unique.
"RowDateField": The name of the field to use as the date for the row, which will appear and be sortable in search results like file modification dates. If no RowDateField is specified, the modification date of the containing file will be used.
"DateFormat": The layout of the RowDateField (example: "YYYY-MM-DD").
"SkipBlankFields": If true, fields with blank values will be omitted rather than being included with an empty value. (This can improve the reada

Fixes/Minor Enhancements:
dtSearch Web: Added support for running dtSearch Web Setup under Windows Server 2025.
Fixed: Some users unable to use Edit > Copy in dtSearch Desktop to copy text from the preview window.
Added search flag dtsSearchWantHitDetailsSynonymOf (In the hits by word report, include SynonymOf= to indicate the source term for synonym expansions.)
Fixed: If MD5Hash or SHA256Hash is designed as a stored field, and if documents are index with the flag dtsoFfGenerateMd5Hash or dtsoFfGenerateSHA256Hash, these field values were not treated as stored fields during indexing for container document types such as ZIP (so the hash values would not appear as document properties in search results).
Fixed: Bug in regular expression matching misses "abc" in a search for "##z*abc". The bug only applies to regular expression searches and affects single character expressions followed by * in cases where the single character expression should match zero instances of the character. In the above example, zabc, zzabc, etc. are found, but abc is not. Simple wildcard searches like z*abc are not affected.
File parser bug fixes affecting: TAR, HWP, HWPX, PDF, EML
Other bug fixes

Fixes and minor enhancements:
dtSearch Desktop indexer now reports image-only PDF files in the index update log. (Metadata in these files is still indexed. This change only affects reporting in the index update log.)
Improved 32-bit indexing performance in low-memory conditions.
Fixed indexing crash in mso20win32client.dll in the latest update to Office 2016 when indexing Outlook messages.

All executables are code signed using SHA-2 in addition to SHA-1 (dual signed). All MSI files are signed using SHA-2 only, because MSI files do not support dual signing. Please see this Microsoft article for more information on SHA-1 deprecation.
Added option in dtSearch Desktop's Edit > Copy File function to automatically shorten excessively long filenames.
Added new C# sample, AjaxWordListBuilder, demonstrating how to use the dtSearch Engine's WordListBuilder object on a web page.

Added support for indexing Apple iWork 2009 Pages, Numbers, and Keynote files

Added support for indexing Apple iWork 2009 Pages, Numbers, and Keynote files

Fixed security issue reported in a third-party component, imgman32.dll, used in the dtimage.exe utility. See http://support.dtsearch.com/faq/dts0235.htm for more information.
Added support for indexing Outlook 2013 and 2010 OST files. Note: Microsoft has not officially documented the OST file format specification, so this support is based on unofficial non-Microsoft information about the OST file format.
Added support for indexing metadata in Adobe Photoshop images
Fixed "~dtpdf.tmp" filenames appeared in tabs in dtSearch Publish
Fixed PDF hit highlighting error in dtSearch Publish on systems with Adobe Reader versions 7-9 and Internet Explorer 10
Added "Images" field at the end of MIME messages listing names of inline image files.
Fixed incorrect handling of filename-only indexing option causing "Unsupported file format" errors
In the API, the flag dtsIndexCreateVersion6 is now ignored, so indexes will always be created in the current index format.

Fixes and minor enhancements:
Updated RAR file parser to support RAR 5
Reduced stack use when indexing very deeply-nested containers
dtSearch Web: Fixed bug in Build Search Form when generating a search form containing a custom field name
dtSearch Web: Fixed bug affecting highlighting of the selected hit when clicking Next Hit in Internet Explorer 8
Some Microsoft Photo Editor 3.0 objects embedded in Office documents were not recognized as image data
File parser bug fixes affecting: .mdb (Access 2003), .msg embedded in .rtf, .xls, .xlsx, .xlsb, .pdf
Other bug fixes.

Added support for indexing iCalendar (*.ics) files
