Drawing search needs metadata before magic

Construction drawing search breaks down when every query is treated as a pure language problem. Teams search by level, trade, revision, drawing number, author, status, and whatever the site calls the place this week.

Breeks uses hybrid search because those signals are complementary. Exact filters keep the result set grounded. Keyword search catches document numbers and titles. Semantic search helps when the user describes intent rather than metadata.

Ranking should be boring

• Same project first.
• Latest revision first.
• Matching trade, storey, and drawing subtype first.
• User-tagged documents should matter.
• Semantic similarity helps, but it should not override obvious metadata.

The result is less theatrical than a pure vector demo, but it is much closer to how project teams actually work.
