You may specify such aliases using the -=#+ROAM_ALIAS= attribute: +To easily find a note, a title needs to be prescribed to a note. A note can have +many titles: this allows a note to be referred to by different names, which is +especially useful for topics or concepts with acronyms. For example, for a note +like "World War 2", it may be desirable to also refer to it using the acronym +"WWII". + +Org-roam calls =org-roam--extract-titles= to extract titles. It uses the +variable =org-roam-title-sources=, to control how the titles are extracted. The +title extraction methods supported are: + +1. ='title=: This extracts the title using the file =#+TITLE= property +2. ='headline=: This extracts the title from the first headline in the Org file +3. ='alias=: This extracts a list of titles using the =#ROAM_ALIAS= property. + The aliases are space-delimited, and can be multi-worded using quotes + +Take for example the following org file: #+BEGIN_SRC org #+TITLE: World War 2 #+ROAM_ALIAS: "WWII" "World War II" + + * Headline #+END_SRC +| Method | Titles | +|-------------+--------------------------| +| ='title= | '("World War 2") | +| ='headline= | '("Headline") | +| ='alias= | '("WWII" "World War II") | + +One can freely control which extraction methods to use by customizing +=org-roam-title-sources=: see the doc-string for the variable for more +information.
