I accidentally added an index on all occurrences of a very common short word. Undoing is no option, I continued editing afte that. It seems libreOffice only allows me to remove them one by one with a lot of manual work.
But it should be possible to write a script which unzips .odt, removes those indexes from content.xml and correctly zips .odt again.
Usage would be
remove_odt_index file.odt targetA targetB …
Does such a script already exist?
There is an example bash script function, of the type indicated in the question, provided in this AOO forum thread. Here is an adapted version:
#!/bin/bash
unzip -p "$1" content.xml | sed -r -e 's,<text:alphabetical-index-mark-(start|end)[^>]*>,,g' > /tmp/content.xml && n="$(basename "$1" .odt)"_removed.odt;
cp "$1" "$n" && zip -j "$n" /tmp/content.xml
Given doc_with_index.odt as input to the above bash script (rm_index.sh), doc_with_index_removed.odt will be written out e.g., $ rm_index.sh doc_with_index.odt
What do you do to add index?
You can select the word in the all document with Find & Replace (Ctrl+F Menu/Edit/Find&Replace).
Search: TheWord
Find all
This select all ocurrences of the word.
Apply the desired format.
