How should I search a mobile extraction report?¶
Start with the investigative question, build an identifier list, then search in stages rather than relying on one broad keyword.
Script¶
A mobile extraction report may contain millions of records.
Searching it well is not the same as typing the suspect’s name into one box and waiting for the answer.
Start with the investigative question.
What are you actually trying to find?
A conversation between two people?
Evidence that an account was used?
A payment reference?
A journey?
A document?
Contact with a particular service?
The question determines the identifiers, date range and artefact categories that matter.
Before opening the search tool, create a short search plan.
List the known people, organisations, places, accounts, devices and events.
For each person, include names, nicknames, usernames, telephone numbers, email addresses and account identifiers.
For each event, include dates, amounts, reference numbers, addresses, domains and distinctive phrases.
Keep the list outside the report so you can record what you have tested.
Then search in stages.
Begin with distinctive identifiers that are unlikely to produce thousands of irrelevant results.
A full email address, unusual username, complete telephone number, transaction reference or uncommon phrase may be a good starting point.
Review where the result appears.
The same value may be found in a contact, chat, browser record, notification, file, application database or system log.
The category and source matter as much as the matching text.
Next, vary the identifier.
Telephone numbers may appear with or without the country code, leading zero, spaces or punctuation.
Names may be shortened, misspelled, transliterated or stored in another person’s contact label.
Email addresses may appear in plain text, account records, login fields, URLs or application databases.
Domains may appear without the full web address.
Use the later identifier-specific cards to build those variations properly.
Now narrow by context.
Use date and artefact filters after confirming how the report handles time.
Search within the relevant application or conversation where possible.
Review nearby records rather than exporting one isolated hit.
The surrounding messages, calls, files or events may explain whether the match is relevant.
Also search across categories.
A reader report’s global search can identify the same term in messages, contacts, images, documents and application data.
That is useful, but it may also return tool-generated labels, metadata and repeated copies.
Treat the first hit as a lead, not a conclusion.
Keep a search log.
Record the exact search term, any wildcard or matching option, active filters, timezone display, report version and number of results.
Record searches that returned nothing as well as successful ones.
A negative result is only meaningful when another person can understand what was searched and which data was available.
Tag or bookmark relevant results using the review tool where appropriate.
Add a short comment explaining why the item matters.
Don’t rely only on the bookmark label. Record the artefact type, displayed time, participants, source path and extraction or evidence source.
If the result is important, preserve it through an export or examiner-supported process that retains context and provenance.
A screenshot may help explain what you saw, but it shouldn’t be the only record.
The common mistake is to search broadly, receive thousands of hits and then review only the first few.
Another is to use one spelling or one identifier and describe the search as complete.
A good search is iterative.
Search the known identifier.
Review the context.
Discover new identifiers.
Add them to the search plan.
Search again.
Then record what you did.
The report is not a search engine that understands the case.
It is a structured evidence viewer.
Your investigative knowledge supplies the connections, but the search process still needs to be reproducible and fair.
Key takeaway
A defensible search records what you looked for, how you varied it, which filters were active and where the result came from.
