Proof points
Indexed documents you can search, chart, and correlate by topic and organization.
Proof points are the underlying records behind Trendtracker signals: patents, news articles, research papers, earnings-call transcripts, PDFs, and grant projects. They come from document indexes, not the knowledge graph.
Use proof points when you need traceability, citations, or document-level filters. For structured deals and company records, use Facts. For grouped real-world events assembled from both, use Manifestations.
Every proof-point dataset exposes the same three shapes:
- Search — a page of enriched documents (
skip/take, max 100). - Time series — counts (and sometimes amounts) per time bucket at a
resolutionofday,week,month,quarter, oryear. - Correlation matrix — co-occurrence of topics and/or organizations. See Correlation matrix.
All of these are POST with a JSON body. Date filters apply to published date.
Shared request fields
| Field | Purpose |
|---|---|
query | Optional Lucene-lite text search (see below) |
topicIds / organizationIds | Scope to topics and resolved organizations |
topicFields | Document fields used for topic matching (default title, summary, body) |
languages | ISO language codes |
sourceIds | Restrict to specific indexed sources |
start / end | Published-date window (ISO datetimes) |
skip / take | Offset paging; take max 100 |
sortColumn | published_at (default) or score |
sortDirection | desc (default) or asc |
Query syntax
query is a closed Lucene-lite expression over document text. Unprefixed words run a loose match on title, summary, and body. Use quotes for a phrase, field: to restrict a clause, and uppercase AND / OR / NOT (or -term) to combine them.
| Example | Meaning |
|---|---|
lithium | Loose match on title, summary, and body |
solid state battery | One loose multi-word match (not an AND of three terms) |
"solid state battery" | Phrase match on title, summary, and body |
title:lithium | Loose match on title only |
title:"solid state battery" | Phrase match on title |
title:(solid state battery) | Loose multi-word match on title |
document:"quantum sensing" | Phrase match on title, summary, and body |
title:"ssb" AND (body:lithium OR summary:anode) | Boolean combination |
(foo OR bar) baz | Implicit AND of already-delimited clauses |
Fields: title, summary, body, and document (all three). After field: use one token, one "phrase", or (...). title:solid state is rejected (a field prefix cannot be followed by extra bare tokens). Wildcards (*), fuzzy (~), and boost (^) are not supported. Lowercase and is a search token, not an operator. Unknown foo:bar is treated as a literal token so values like covid-19 stay valid.
