What this category's data looks like
In self-funded study abroad application services, materials usually enter through three routes: study abroad service contracts, school application forms, and personal statements, each carrying fields, dates, and signatures. Contracts focus on service scope, fees, and signing date; application forms focus on institution, major, intake season, and submission time; personal statements focus on version, revision records, and finalization status. The update rhythm is driven by application rounds, and it is common for the same record to have mismatched names, quantities, and dates across two materials, unsynchronized versions, and missing signatures or receipts. When entering this feature, contracts and application forms serve as source materials for the basis, while personal statements serve as supplementary materials that can be traced back to the original text; together, the three support basis entries and source tracing.
Configuration and implementation checks
This step is executed by the indexing service and vector database, outputting vectors and index status (whether recall is possible and whether data in the same group is merged). "Basis entries that can be traced back to the original text" are then completed by subsequent AI nodes, code nodes, or manual work (retrieval and citation trimming only take supporting materials).
| Object | Check | Verification action |
|---|---|---|
| Study abroad service contract | Fields, dates, and signatures must match the application form and personal statement; signing date and receipt must not be missing | Open the contract data row, check whether the index field records multiple vector identifiers, and confirm the status is indexed |
| School application form | Institution, major, intake season, and submission time must be consistent with the contract and personal statement, and dates must not have two versions | Retrieve this material, see whether the same group of data is merged, whether the vector score takes the highest value, and record the coverage scope of the rebuild task |
| Personal statement | Version and finalization status must be synchronized with the contract and application form, and revision records and signature receipts must be complete | Sample a data row to inspect the index field, then retrieve once more to see whether the same group is merged, and check the reference budget of limit |
| Index model | Must be consistent with the vector model actually used by the knowledge base; after changing models, only trigger rebuild for data that has already been indexed | Check the index model in the knowledge base settings, and inspect the data scope covered by the rebuild task records |
Three common errors
- Symptom: duplicate entries appear in retrieval results. Inspect the following: the same record has mismatched names, quantities, and dates across two materials, and vectors are not merged according to the same group of original data.
- Symptom: recall quality drops after changing models. Inspect the following: versions are not synchronized, the rebuild task only covers data that has already been indexed, and the uncovered part still uses old vectors.
- Symptom: a data row has content but cannot be retrieved. Inspect the following: signatures or receipts are missing, the material has not entered an indexable state, and the index field does not record the corresponding vector identifier.
How to verify the setup
This feature acceptance: sample a data row to inspect the index field and confirm that multiple vector identifiers are all present; then retrieve once more to see whether the same group of data is merged, whether the vector score takes the highest value, whether the status is indexed, and inspect the rebuild task records.
Business test: ask a cross-material basis question, see whether the answer gives traceable sources, and check that the number of citations is the array length and quoteMaxToken is the reference content budget; do not compare the two for equality.
- In the knowledge base settings, check that the index model is consistent with the vector model actually used, and inspect the data scope covered by the rebuild task records.
- Open a data row to check the index field, confirm that multiple vector identifiers are all present, and record the reference budget of
limit.
