For books, try these subject headings:
Conservatism -- (Continent/Country)
In article databases, brainstorm issues and topics that compose the mindset of current conservatism. Try searches like these:
- (conservatism OR conservative politics OR right wing) and (country)
- (conservati* OR right wing) AND (economic policy)
- (conservati* OR right wing) AND (healthcare)
For age-based analysis, brainstorm keywords to describe the population that you are looking to analyze. Try things like:
- (conservati* OR right wing) AND (gen z OR generation z OR teens OR young adults)
- (consertavi* OR right wing) AND (millennials OR adults)
Keep in mind that words like "effective" or "benefits" will not significantly help search results - they are too vague.
