            Bug ID: 311045
          Severity: wishlist
           Version: 0.15.3
          Priority: NOR
          Assignee: okular-devel at kde.org
           Summary: Search strings should be parsable from the
                    command-line
    Classification: Unclassified
                OS: Linux
          Reporter: comeniusmar at gmail.com
          Hardware: Ubuntu Packages
            Status: UNCONFIRMED
         Component: PDF backend
           Product: okular

Evince offers a command-line argument that allows users to parse a search
string into the search field. For instance,

evince --find=searchterm document.pdf

will open the document with "searchterm" in the search field. Invoking the
search field  - e.g. by hitting CTRL+F - then searches through the document for
"searchterm".

The key application of this feature is the integration of PDF viewers into
document indexers such as Recoll
(http://www.lesbonscomptes.com/recoll/release-1.18.html). 

As of its newest release, Recoll supports the indexing of phrases in the
context of their position within the document. If a corresponding match is
found Recoll directly parses the page number and the stemmed search term to
evince. You can see the feature in action here:

One important note: Evince only searches through the document after activating
its search field. This option is important as searching through large PDF
documents can be ressource heavy at times. If the instance of the search term
is obvious enough on the page, e.g. in case of a heading,  a search  might be
unnecessary. Giving the user the option to either use the automatic search or
manually scan through the page for the search term alleviates this.

Proposal:

Add a command-line option akin to the one in Evince, which allows parsing
search terms to Okular's search field. Optionally add a command line switch
that determines whether Okular immediately engages in a search upon opening the
document or only after activating the search field.

Summary: 

Adding a command-line option to parse search strings into okular would
significantly improve its integration with powerful indexing tools such as
Recoll

Reproducible: Always
