Error message

ctrip search

What it means

An EmptyResultError thrown by `ctrip search` when Ctrip's suggest API returned data, but after filtering and mapping (mapSuggestRow), no row had a usable `name` — i.e. the search keyword matched nothing usable. The message suggests trying a destination, scenic spot, or landmark keyword such as 苏州 or 故宫.

Solutions

1. Retry with a well-known Chinese destination keyword such as 苏州, 故宫, or 三亚
2. Use the destination's Chinese name rather than pinyin/English
3. Shorten the query to the city or landmark core (e.g. 马尔代夫 instead of 马尔代夫某岛)
4. Catch EmptyResultError and fall back to a broader keyword in your script

Example fix

// before
const rows = await runCli('ctrip', 'search', keyword); // throws when empty
// after
let rows;
try {
  rows = await runCli('ctrip', 'search', keyword);
} catch (e) {
  if (e.name === 'EmptyResultError') rows = await runCli('ctrip', 'search', fallbackKeyword);
  else throw e;
}

const KNOWN = ['苏州','北京','三亚','故宫','马尔代夫'];
if (!q || q.length < 2) console.warn('keyword may not match Ctrip suggest; consider a known destination');

try {
  const rows = await runCli('ctrip', 'search', keyword);
} catch (e) {
  if (e.name === 'EmptyResultError') {
    const rows2 = await runCli('ctrip', 'search', broaderKeyword);
  } else throw e;
}

When it happens

Trigger: Calling `opencli ctrip search <keyword>` where fetchSuggest(query, 'D') returns rows that are all non-objects, filtered out, or map to rows without a name — e.g. misspelled place names, single Latin letters, brand names, or extremely obscure keywords Ctrip's destination suggest does not know.

Common situations: Typo'd or romanized keywords ("sanya" instead of 三亚); searching for hotels or restaurants rather than destinations; keywords in a language Ctrip suggest does not index; overly specific multi-word queries.

Understand the failure class

Background: EmptyResultError / "no results found": when an API or scraper succeeds but returns zero rows — this error's family across 9 libraries.
