Function astTest

astTest(query: string, options?: AstProbeOptions): Promise<AstProbeResult>

Runs an advanced (boolean) query against every cached product title through the real parseSearchQuery → scoreAstMatch path, showing which titles the predicate keeps, which it drops and why, and which drops hinge on fuzzyWords.

Parameters

query: string
The search string; may use AND/OR/NOT and parentheses.
options: AstProbeOptions = {}
source ("cache" / "results" / "both"), suppliers, limit (0 = all), ranking scorer, threshold, fuzzyWords, and compareFuzzyWords.

Returns Promise<AstProbeResult>

The full evaluated result, also printed unless print: false.

Example

// In the console:
const result = await chempal.astTest("sodium AND NOT borohydride");
result.astText;                 // => '(sodium AND NOT borohydride)'
result.matched.length;          // => 37
result.dropped[0].failedTerms;  // => ['sodium']

await chempal.astTest("acid OR base", { fuzzyWords: false, threshold: 70 });
await chempal.astTest("sodium", { suppliers: "loud", source: "cache", limit: 0 });

Source

export async function astTest(
  query: string,
  options: AstProbeOptions = {},
): Promise<AstProbeResult> {
  const corpus = await collectCachedTitles(options.source);
  const result = evaluateCorpusAst(query, corpus, options);
  if (options.print !== false) {
    printAstProbe(result, options.limit);
  }
  return result;
