toUpper
Generic Description
Is the Cypher-style uppercase alias. It is documented separately because text normalization and slicing often become grouping keys, search inputs, or exported identifiers.
Simple example:
RETURN toUpper('runbook') AS value
Consumer-Level Explanation
Use it when a query already uses to* conversion spelling and should keep that style. Prefer this function when the text operation is part of the query contract and should be visible during review.
More Detailed Explanation
toUpper runs inside the row pipeline, which makes text cleanup, extraction, and grouping keys visible to Nexyron instead of hidden in application code. That is especially important for imported document metadata, labels, and identifiers that feed later matching or indexing.
Advanced Example
This example applies toUpper while shaping document metadata, so text cleanup is part of the auditable query rather than an application-side afterthought.
MATCH (d:Document)
RETURN d.title AS title, toUpper(properties(d.metadata).kind) AS content_kind_code
ORDER BY content_kind_code
Real Use Cases
- normalizing document titles and source identifiers before grouping
- extracting prefixes, suffixes, or tokens from imported text fields
- checking payload size or Unicode normalization before ingestion cleanup
Real Limitations And Tradeoffs
- query-time cleanup is explicit but can hide upstream data-quality debt if overused
- string operations are not semantic search; use vector or semantic procedures for meaning-based matching
- byte length and character length answer different questions and should not be substituted blindly
