The search protocol then follows a three-staged process of execution: identification, screening and extraction.
First, in identification, the above categorizations are combined through Boolean operators to conduct a search through the database repository Web of Science.
<!-- TODO why WOS database? -->
The search istelf is conducted with English-language search queries only.
<!-- TODO grey lit? -->
The search itself is conducted with English-language search queries only,
connecting the various clusters with logical 'and' connectors, excluding partial matches,
while synonymous or related terms are connected with logical 'or' connected, allowing partial matches.
<!-- TODO will we be using lit? -->
The search may also include other database repositories such as Google Scholar,
in order to catch possible grey literature.
For database repositories which do not allow a precise enough query,
splits are introduced at term cluster edges,
in order to enable later intersection joins (or 'inner merges') based on common DOIs, URLs or a combination of author and title.
Relevant results are then complemented through the adoption of a 'snowballing' technique,
which analyzes an array of published reviews for their reference lists to find cross-references of potentially missing literature.
<!-- TODO AUTOMATE NUMBER GENERATION -->
The execution of queries results in an initial sample of 2169 studies after the identification process.
Currently execution of queries would result in an initial sample of 2169 studies after the identification process.
The majority of studies result from the 'income' inequality cluster of the boolean search,
with horizontal cluster terms used often but rarely on their own.

Similarly, if a specific type of inequality,

these will be reflected in the same keyword system, through for example 'inequality::income' or 'inequality::gender'.

The complete process of identification and screening is undertaken with the help of the Zotero reference manager,
ultimately leaving only publications which are relevant for final full-text review and analysis.
