“investigate” the issue
1. carry out a systematic or formal inquiry to discover and examine the facts of (an incident, allegation, etc.) so as to establish the truth.
“police are investigating a claim that the man was beaten unconscious by a gang”
2. carry out research or study into (a subject or problem, typically one in a scientific or academic field).
“future studies will investigate whether long-term use of the drugs could prevent cancer”
3. make inquiries as to the character, activities, or background of (someone).
“everyone with a possible interest in your brother’s death must be thoroughly investigated”
4. make a check to find out something.
“when you didn’t turn up I thought I’d better come back to investigate”
I recommend using ‘look into‘, ‘examine‘ instead of ‘investigate‘ when talking about a technical issue.
