|-
|| '''Visual Cue'''
|| '''Narration'''
|-
|| Slide: Title
|| Welcome to this''' '''Spoken Tutorial on '''General Settings''' in''' DSpace.'''
|-
|| Slide: Learning Objectives
|| In this tutorial, we will learn to
* Index the full text of '''Item '''files
* Generate a '''thumbnail''' for the '''Item''' files
* Enable '''User Interface language switcher''' and
* Localize the '''User Interface '''of '''DSpace'''
|-
|| Slide: System requirements
|| This tutorial is recorded using
* '''Ubuntu Linux OS 18.04'''
* '''DSpace version 6.3'''
* '''gedit text editor''' and
* '''Firefox web browser'''
However, you may use any other '''web browser '''and '''text editor '''of your choice.
|-
|| Slide: Pre-requisites
|| To practice this tutorial, you should have
* A working '''internet''' connection
* Installed '''DSpace 6.3 '''on your system
* '''Tomcat services''' should be running
|-
|| Slide: Pre-requisites
||
* Some archived '''Items '''in the '''Collection '''
* If not then please go through the prerequisite tutorials on this website.
|-
|| Slide : Code files
||
* The''' '''files used in this tutorial are available in the '''Code Files '''link on this tutorial page.
* Please download and extract the file before practising.
|-
|| Slide: Search in '''DSpace'''
||
* '''DSpace '''offers a '''Search''' feature for searching '''Items '''by '''keyword'''.
* By default, '''DSpace''' indexes the '''metadata '''of the '''Items '''and uses it for '''Search'''.''' '''
* '''Items '''are searchable if the '''keyword''' is available in the '''Index'''. i.e. the '''metadata'''
|-
|| Slide:Full text Indexing for '''Items'''
||
* '''DSpace''' can also index the full text from '''Item''' files using add-on '''Media Filters'''.
* Full text '''indexing''' makes the '''Item''' searchable with any word in the '''Item''' file.
|-
|| Slide: '''Media Filters'''
|| '''Media Filters''' can extract text from the following '''formats'''.
* '''Adobe PDF''' (only if text-based or '''OCRed''')
* A '''Document, Spreadsheet''', or '''Presentation'''
* Plain text and
* '''HTML'''
|-
|| Slide:''' Media Filters'''
||
* Additionally, the '''Media Filters '''generate '''thumbnails '''for the '''Bitstreams/ Item Files.'''
|-
|| Only Narration
|| Now, let us examine the '''Search''' feature without the full-text '''indexing''' of '''Item'''.
|-
|| Open '''HPC-Article.pdf''' file
|| Earlier in this series, '''HPC-Article.pdf '''file was uploaded as an '''Item '''in the '''Article Collection.'''
|-
|| Highlight '''Signal Processing''' word
|| Now, choose any '''keyword''' from that file, which doesn’t belong to the '''metadata '''of the '''Article'''.
So, let us choose “'''Signal Processing” '''as the''' keyword'''.
|-
|| Only Narration
|| Now let us proceed to search the '''Item''' using this '''keyword'''.
|-
| | Open Web Browser
| | Open a '''web browser.'''
|-
| | '''Go to localhost:8080'''

| | Click on the '''Search''' icon next to the '''search bar'''.
|-
|| Point to '''Search''' page
|| The''' search '''page opens.
|-
|| Point to “'''Search produced no results'''”
|| The '''search''' produced no results because the words “'''Signal Processing” '''was not '''indexed'''.
|-
|| Only narration
|| Now, let us proceed to '''index''' the full text of the uploaded files using the '''media filters.'''
|-
|| Switch to '''gedit''' text editor and open the file
|| I have opened the '''commands '''file in the '''gedit text editor''' on my machine.
Please do so on your machine also using your preferred '''text editor'''.

If prompted, type the '''root user password.'''
'''Media filtering''' has begun for all the uploaded '''Item''' files.
It may take some time depending on the number of '''Item''' files.
|-
|| Only Narration
|| '''Media filtration''' is now complete.
|-
|| Point to '''HPC-Article.pdf.jpg''' file
|| Observe that the '''media filter''' has created a '''jpg '''image for each '''Item''' file.
These '''jpg '''files are used as '''thumbnails''' for the '''Item''' files.
|-
|| Point to '''HPC-Article.pdf.txt''' file
|| '''txt''' files are also created for each '''Item''' file and the contents of the '''txt '''files are '''indexed''' for '''search'''.
|-
|| Only Narration
|| Next, we’ll proceed to search an '''Item '''using the '''keywords “Signal Processing”.'''
|-
|| Switch back to '''DSpace'''
