<abstract> function in Vortex
is improved in Texis
version 6. Multiple "snippets" of a query may now be returned. This
means that if a query contains multiple terms, and they only occur
widely separated in the source text, multiple sections of the document
may be returned (separated by ellipses), to show occurences of more of
the query terms. Previous versions would return a monolithic abstract
containing only one of the terms, or perhaps between terms.
Leading/trailing ellipses are also added in version 6, if parts of the
document before/after the abstract were removed. Handling of file
paths and URLs is also improved. New modes
querybest were added; see the Vortex manual on
<abstract> for details.
The version 5 behavior (monolithic return value) can be obtained
