Search words, quoted phrases, and exact IDs across the current corpus.
By default, all meaningful words must match the same source passage, in its text or titles. Matching ignores letter case. Ordinary word queries skip common English function words such as the, and and or; quotes keep a phrase, and uppercase operators control matching.
| Example | What it does |
|---|---|
controlled variation | Requires both meaningful words; their order may differ. |
"controlled variation" | Requires adjacent words in that order. |
SYSE.24:4 | Prioritizes the exact named section. Pattern IDs also work. |
engineering OR management | Matches either alternative. Write OR and AND in uppercase. |
engineering AND (research OR management) | Requires engineering together with either grouped alternative. |
engineering -management | Excludes passages that match management. |
title:"controlled variation"body:"controlled variation" | Restricts the phrase to section/publication titles, or to source text. A field prefix applies to the following term or phrase. |
"controlled variation"~1 | Allows one intervening word in the phrase. |
"controlled vari"* | Requires adjacent words, with the last word as a prefix. |
engineering^2 OR management | Gives engineering matches more ranking weight. |
The Publication, Suite and Type filters narrow the same query. Results are source passages, not generated answers. Search does not translate, expand synonyms or automatically correct spelling. For a task expressed in another language, try English terms and read the context. Press / to focus the search field.

PSDA.6:9 - Consequences The comparison becomes open about what it values and what it cannot exchange. Simplifying the account can reduce burden without losing material distinctions. Some decisions remain partially ordered or disputed; that is a truthful…
