Guide
Worked exercise · Separate revision from addition in a rise
Fictional example: the values and documents teach the method and do not describe a real organisation. Keys are unique, values additive and the dictionary unchanged. Nothing is deleted; “absent” means no such key in that version.
Guide
Worked exercise · A comma inside a name is not a column
Fictional example: the values and documents teach the method and do not describe a real organisation. The delimiter is a comma. A colleague proposes splitting at every comma; the code must remain text.

Worked exercise · A correction changes the result, not every citation
Fictional example: the values and documents teach the method and do not describe a real organisation. The correction notice replaces the denominator. The secondary record has not yet incorporated the change.
Guide
Worked exercise · A name change does not create a second association
Fictional example: the values and documents teach the method and do not describe a real organisation. RNA-A is a fictional label, not a real register number. The directory counts X and Y as two entities; examine the notices before counting them.
Guide
Worked exercise · An invalid response does not explain its cause
Fictional example: the values and documents teach the method and do not describe a real organisation. The result concerns a fictional number. Its cause has not been established; examine the scope of the proposed conclusion.
Guide
Worked exercise · An authorisation number copied into a message
Fictional example: the values and documents teach the method and do not describe a real organisation. The message claims to come from the registered company. No independent link between its sender and that company has been established.
Guide
Worked exercise · Planned enrolment, actual enrolment and results differ
Fictional example: the values and documents teach the method and do not describe a real organisation. All information concerns the same fictional record. Determine what can be calculated and what remains unknown.
Guide
Worked exercise · A CSV licence does not automatically cover its photo
Fictional example: the values and documents teach the method and do not describe a real organisation. You want to publish a chart based on the CSV and reuse the photograph on the same page. Terms apply to the objects shown.
Guide
Worked exercise · Annual and monthly amounts may be equivalent
Fictional example: the values and documents teach the method and do not describe a real organisation. Both records describe the same budget scope, year and twelve full months. Compare their values before adding them.
Guide
Worked exercise · Four unreadable answers are not four missing citations
Fictional example: the values and documents teach the method and do not describe a real organisation. Panel categories are disjoint. An unreadable answer is not an observed absence of citation.
Guide
Worked exercise · A file absent from HTML still feeds the build
Fictional example: the values and documents teach the method and do not describe a real organisation. source.csv appears in no rendered page. The current index works; the monthly script still reads this source to build the next index.

Choose a starting point

Choose a method

Start from a task: verify, compare, document or decide.

Check a source

Examine the origin, date, scope and limits of information.

Understand a term

Find definitions before applying a protocol.

How can I refine the search?

Start with the topic: Enter one or two specific terms: citation, CSV or provenance. Every word must be present, so a long sentence can exclude useful pages.
Broaden before filtering: Search all families first. Then select a guide, protocol or source according to the kind of answer you need.
Try different wording: Try a synonym or a term in the selected language. Quotes, OR and asterisks are not search operators.

DEEPER READING / PRACTICE

Turn internal search into a useful user journey

A query produces several close results. Reading should help to distinguish the need definition folder, detailed method and implementation tool.

Updated on 2026-10-21.

Priority checks

Formulate a specific need and then try neighboring terms. Read the descriptions and select the type of resource according to the searched step: understand, run or control.

Interpretation pitfalls

The first result is not always the best document to the context. An absence can come from the vocabulary used rather than a lack of content.

Working record to retain

A short route connects a need definition page, a guide and a checklist. Maintaining unresolved questions helps to rebuild research.

PRACTICAL CASE / WORKED EXAMPLE

A natural requirement does not match the exact title

The following case illustrates an approach to defining the need. Situations are pedagogical: they serve to examine the choices and conditions of success, without describing a fulfilled mission or announcing a guaranteed result.

Example context

A reader is looking for how to check a number, while the resources use the word indicator. The results must allow to continue despite a different formulation of the title.

Suggested approach

Try the neighboring terms and read the descriptions. Differentiate methods of calculation, comparison and verification of sources. Choose the resource that corresponds to the actually sought-by-step.

Conclusion and next step

Research becomes a path of solution. The questions still open serve to clarify the next query instead of multiplying the words without clear intention.

Questions for deeper practice

How do you improve a search without losing the initial need?

Keep the starting question and then specify the object, operation and resource type. Useful results give a complementary vocabulary, but their title should not automatically replace the reader's target.

DETAILED WORKSHOP / APPLICATION

Refine a query for the task to carry out

01 / Prepare the necessary information
Describe the initial question and the desired result. Identify the object, operation and type of resource that could help: file, method or tool.
02 / Carry out the approach
Try a formulation and read the descriptions. Release the useful terms and test the variants without giving up the intention. Compare the resources found according to their contribution to the route.
03 / Examine an alternative situation
If the results are close but too general, specify the operation or scope. A well-classed page is not necessarily the one that meets the searched step.
04 / Decide on the next step
Research is useful when it leads to a resource whose response can be identified. Open questions are used to prepare for the next consultation.
05 / Hand over the verification records
Keep a short track with request, resource and supplement. The reader can restart his work without repaired the tests that have led to useful content.

ANNOTATED WORKING DOCUMENT / REVIEW GRID

A track record from a request

The note retains question, tried formulations, useful results and next resource. It distinguishes the exploration vocabulary from the initial goal of the reader.

On a small screen, scroll the grid horizontally to read all three columns.

Example situations to assess
Observation	Supported interpretation	Next step
A resource responds to the desired operation.	The result can serve as a useful step in the course.	Keep the passage and choose the necessary supplement.
The results remain general despite the good topic.	The request must specify action, object or scope.	Try an appropriate formulation without losing the initial question.
The first result has the word but not the answer.	The presence of the term does not prove its relevance.	Read the descriptions and compare the contribution of resources.

Reviewing the working document

The final verification verifies that each step reduces an open question. A link list is not yet a useful path if the reader cannot explain what each page brings.

REPORTING / EXAMPLE WORDING

Presentation of results: Turn internal search into a useful user journey

Point to clarify

A search result must be judged according to its contribution to the searched operation.

Before handing over

Check that the track keeps the initial question despite the vocabulary variants.

Example of a qualified conclusion

The resource selected meets the described stage of the need. The questions still open guidelines the next consultation and remain distinct from the answer found.
